Description
If I hide some of the windows from CCNav default layout, and when I press any line of code in the "SourceCode" view to get the corresponding assembly, it works but a window alert occurs telling "TypeError: Cannot read properties of null (reading 'appendChild')". Here is a screenshot of this.

Maybe this was done intentionally for debugging and forgot to remove the window.alert() line?

Research direction
Reproduce the issue in the CCNav default layout after hiding windows, then click a code line in the "SourceCode" view and inspect the GoldenLayout-related path that handles the assembly display. Done means the corresponding assembly still appears without the null-reference alert when windows are hidden; no test file is named in the issue.
