in textMutationObserver, we will go through mutations that is not made by content model and see if we can reconcile the change and reflect it in existing cached Content Model. And if an mutation happens under an entity, we should ignore it.

However, it is possible that we delete an entity node from editor and modify some node under this deleted node. Now when we handle this mutation, since the target node is already removed, existing code will return false when we check if it is under an entity. This causes the mutation won't be ignored and finally an existing cache will be invalidated.

Fix: Check if the target node is under editor. If so, directly ignore this change. So cache can be preserved.

* Fix #3280 (#3282)

* [Table Improvements] Ignore span cells when merge table cells (#3281)

When merging table cells, count table that are span as one cell, so two or more cells cannot be merge to one single span cell.

* Preserve cursor position when navigating tables  (#3284)

When pressing key up or key down in table cells that have text, preserve the cursor position.

* Add adjustWordListMarginParser to fix duplicate list indentation when pasting from Word Desktop (#3288)

Word Desktop pastes list items with full indentation as marginLeft on MsoListParagraph
elements, which duplicates the paddingInlineStart (40px) already applied by the
browser's default list styling. This parser subtracts the default 40px from the
marginLeft of list items with the MsoListParagraph class to correct the indentation.

- Add adjustWordListMarginParser using parseValueWithUnit for unit conversion
- Register parser for listItemElement in processPastedContentFromWordDesktop
- Update addParser call count expectations in pasteTest and ContentModelPastePluginTest
- Add dedicated test case for the margin adjustment behavior

* Preserve trailing space in last paragraph segment by converting to nbsp (#3235) (#3287)

* Preserve trailing space in last paragraph segment by converting to nbsp

When the last text segment in a paragraph ends with a regular space,
browsers collapse it during rendering. This change detects that case in
handleText and replaces the trailing space with a non-breaking space
(\u00A0) so it is preserved in the output.

To support this, a new ModelToDomSegmentContext interface is introduced
that extends ModelToDomContext with an isLastSegment flag. handleParagraph
sets this flag for each segment before dispatching, and ContentModelSegmentHandler
is updated to use ModelToDomSegmentContext as its context type, eliminating
the need for type casts in the handlers.

* Improve trailing space to nbsp conversion with noFollowingTextSegmentOrLast

Refactor handleParagraph to track whether a text segment is the last in the
paragraph or has no following text segment (excluding SelectionMarkers).
This ensures trailing spaces are converted to &nbsp; not only for the very
last segment, but also when the next non-marker segment is not a Text segment.

- Convert forEach to for loop in handleParagraph for segment iteration
- Extract hasTextSegmentAfter helper to check for upcoming text segments
- Add noFollowingTextSegmentOrLast property to ModelToDomSegmentContext
- Update handleText to use the new property name
- Fix stale isLastSegment references in handleTextTest
- Add comprehensive tests for noFollowingTextSegmentOrLast in handleParagraphTest
