Research direction

Start by reproducing the issue on the main site: display a variable monitor and open its context menu. Then trace the monitor and context-menu entry points in the editor to find what causes the editor height to change. Done means opening the menu no longer shrinks the editor.

Written by the indexing model from the issue text.

Description

Expected Behavior

The editor should probably stay the same height.

Actual Behavior

The editor shrinks (???)

Steps to Reproduce

  • Go to any project on the main site, or create a fresh one (quicker).
  • Display a variable monitor.
  • Context click (The one that brings up a menu, typically the right mouse button, or holding using a touch input) on the monitor.
  • And then, behold:
