- Around line 587-595: Update the scrollability test around menuCategory to
exercise the interaction path: scroll the final non-parent menu item into the
dropdown’s visible area, click it, and assert that the dropdown closes. Retain
the overflow assertion, but replace the visibility-only check with assertions
that validate the user-facing selection behavior.

Why set showDropdown = true before present()?
The real need is to clear hidden on slotted items before overflow is measured (onShowItemsChange). Setting show early can open the dropdown even if willPresent() / showChange was canceled. Can we unhide the items directly and keep showDropdown synced from showChanged?

Good point, though on the flip side, it's not good to manually set hidden for all children without it being clear where or why that's happening and bypassing existing mechanisms for doing that.
I prefer implementing a separate flag, willShowItems, that signifies the intermediate period for preparing to show menu items, which is what this is, and connecting that to the existing logic for hiding the sub-menu items

Please rename the PR title to conventional format: fix(core/menu-category): … (see .github/instructions/code-review.instructions.md). |

Consider to add Fixes #2664 to the changeset summary so the issue closes on release. |
Ensure sub-menu items are visible before dropdown presents to enable correct scrolling behavior when no category item is active. This addresses issue #2664.

Replace the arbitrary animation delay.
Line 614 uses page.waitForTimeout(300). Poll menuItems.evaluate((el) => el.style.maxHeight) until it returns '', then assert the expanded state.

💡 What is the current behavior?
If an application sub-menu contains enough items to create a scroll, the scroll is only visible when the user is on a page that is in that sub-menu. If the user is on a page that is NOT inside the long sub-menu, and then hovers on the main nav menu item that contains the sub-menu, then the sub-menu scroll is not visible and items in the sub-menu are not clickable
GitHub Issue Number: #2664
🆕 What is the new behavior?
Fix the bug by setting showDropdown to true before the dropdown children and scroll are calculated
