Getting merge conflict when saving from in-place edit mode after updating document fields from the Information tab

Same steps as XWIKI-23262. After saving the new syntax, make some changes to the document content and save. You get a merge conflict. The root problem is that the syntax change incremented the document version, but this has not been propagated / announced by triggering the xwiki:document:changeVersion event, so the WYSIWYG editor on the same page is submitting the content with the previous document version, causing a merge conflict.

This can be fixed by modifying editableProperty.js to trigger the xwiki:document:changeVersion event, but we can't call meta's setVersion unless the edited property is from the current document, which might not be always the case (it's possible to edit on page X a property from page Y).
