* Presence of the aside no longer affects position or size of the
context menu.
* Prefers to fit to the right, then on same side of line, then other
side of line, within the following preference order:
- Max possible size within text area.
- Max possible size within window.
- Actual size within window. This is the only case that could cause it
to jump around with less stability.
A further enhancement atop this might be to dynamically resize aside
height to fit.
Release notes are N/A as they are covered by the notes for #22102.
