Description

If you open two split notes with a code note on one side and a text note on the other, switching the focus from the text note to the code note by clicking on the code note doesn't always update the focused tree branch.

This doesn't always repro, but it reproes more easily if you click on a closing brace or on a word of the code note, both of which require the code note editor to perform some extra work highlighting.

When the error happens, the javascript console shows a timeout handler and reflow warning

[Violation] 'setTimeout' handler took 94ms
[Violation] Forced reflow while executing JavaScript took 62ms

This also breaks the widgets that depend on reporting that change, since the widget's isEnabled method is not called in that case. This was found while developing the TOC widget, see #2799 (comment) .

The following video shows how the tree fails to focus several times when switching from the text note to the code note by clicking on the editor panes. When that happens, the widget's isEnabled that has a console.debug() output also fails to appear in the javascript console.
