Bumps mermaid from 11.17.2 to 12.2.0.

Release notes

Sourced from mermaid's releases.

mermaid@12.2.0

Minor Changes

• #8394 6ac38cb Thanks @​jackroberts236! - feat: Add opt-in mindmap coloring by hierarchy depth using mindmap.colorBy: depth and the existing theme palette.

Patch Changes

• #8409 419ee68 Thanks @​ashishjain0512! - fix: size circle and double-circle nodes from their label instead of minNodeWidth, and trim neo circle padding

• #8395 2fb3ff1 Thanks @​ashishjain0512! - fix: ELK no longer straightens an edge terminal when that would put a label over another edge, or an edge through a label

• #8394 cbf89ab Thanks @​jackroberts236! - fix: Keep mindmap HTML labels readable in the neo look on themes that repaint node backgrounds

• #8390 430ac9b Thanks @​ashishjain0512! - fix: Centre mindmap node labels when htmlLabels is false

• #8161 d7532ed Thanks @​filipsajdak! - fix: scope a swimlane cluster's DOM id like every other cluster, so two diagrams on one page do not collide

• #8270 ad8d61a Thanks @​filipsajdak! - fix(rendering): clip an edge for the layout engine that drew it, so a diagram pinning its own engine (bpmn, swimlanes) still renders when the configured default is another one

• #8383 9d41c0f Thanks @​filipsajdak! - fix(swimlanes): split shared terminal lanes again after crossing cleanup, so an edge that detours around another lane no longer ends on the same attachment point as a neighbouring edge

• #8384 6c67397 Thanks @​filipsajdak! - fix(swimlanes): move a lane's title band clear of an edge that crosses it, in LR diagrams whose lanes carry no direction of their own and when the edge runs along the band's border

• #8366 40124c3 Thanks @​SwastikTripathi! - fix: swimlane nodes with no edges keep their source order inside a lane instead of being sorted by ID

mermaid@12.1.0

Minor Changes

• #8303 9140716 Thanks @​filipsajdak! - feat: add the elk.orientFeedbackEdges option, enabled by default. With the ELK layout, an edge from a node that a subgraph feeds back into that subgraph is now routed downstream instead of around the subgraph. This changes the layout of existing ELK diagrams that contain such edges; set elk.orientFeedbackEdges: false to keep the previous routing.

• #8250 fd4f5f2 Thanks @​kartben! - feat: add a bitOrder option to packet diagrams. It defaults to ascending, which is the current behaviour, and descending mirrors every row so it reads from that row's highest bit down to its lowest. Fields are still declared lowest bit first and keep their width, so switching a diagram between the two conventions only means changing bitOrder.

Patch Changes

• #8330 50c9e55 Thanks @​ashishjain0512! - fix: upgrade chevrotain to 13 so mermaid no longer pulls in vulnerable lodash-es@4.17.23

• #8259 4c90f5c Thanks @​afonsojanu! - fix(sequence): allow whitespace between an actor name and its @{ ... } config object

  participant Bob@{ "type" : "database" } parsed fine, but adding a single space before the config object (participant Bob @{ "type" : "database" }) failed with a confusing parse error, even though the plain form without a config object tolerates trailing whitespace just fine.

• #8339 c7fa1a5 Thanks @​ashishjain0512! - fix: keep ELK class-diagram cardinalities off namespace frames

• #8334 d67331d Thanks @​ashishjain0512! - fix(class): place cardinality labels beside their relation ends on dagre's sides with ELK, centre dagre's end labels, and stop clipping their text

• #8344 99a050b Thanks @​pbrolin47! - fix: with the ELK layout, an edge label could sit up to 16px beside its edge instead of centred on it, when the edge's terminal jog was straightened after the label's position was computed. The label is now re-projected onto the straightened route

Preserve the previous Mermaid layout for existing diagrams

Mermaid 12 changes the default layout engine from Dagre to ELK, so every existing flowchart, state, class, ER, requirement, and use-case diagram that does not specify a layout will render with a different structure after this dependency bump. RichContent.tsx initializes Mermaid without a layout override, and the application renders arbitrary stored/AI-generated diagrams, so this causes a visible regression in previously rendered content; set layout: "dagre" (and the prior theme/look where needed) or explicitly accept and test the new layout. See the Mermaid 12 release notes.

@dependabot ignore this major version

[gansx]

留在 mermaid 11：mermaid 12 引入 elkjs（EPL-2.0），当前许可证策略不允许。如后续需要 mermaid 12，先单独评审 elkjs 的许可证例外再升。

[dependabot]

OK, I won't notify you about version 12.x.x again, unless you re-open this PR.
