[bug][minor][2.4.0] Selecting multiple annotations and modifying properties results in only last annotation being modified #177

Describe the bug
Selecting multiple annotations and trying to modify their properties in one go results in only last annotation interacted with being modified.
"Interacted with" can be either "added to selection last" or "removed from selection last", with latter being modified even if not selected at all anymore.

To Reproduce
Steps to reproduce the behavior:

1. Add two or more annotations, regardless being of type text or shape.
2. Select all those annotations.
3. Right-click and select "Properties".
4. Modify any property.
5. Error: Only the annotation interacted with last is being modified.

Expected behavior
All annotations being selected change their visual state.

Screenshots
