Search Editor Progress Bar Animates Endlessly After Search Completed (intermittent)

[karlhorky]

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.92.1 Commit eaa41d5
• OS Version: macOS Sonoma 14.6.1 (23G93)

Steps to Reproduce:

1. Perform a search using the VS Code Search Editor
2. Intermittent: Blue progress bar / indicator animates endlessly, even after search is completed (I have not yet identified a pattern for which search terms trigger this) - almost like hanging behavior, but everything is still responsive.
3. Reloading the editor using "Developer: Reload Window" causes the problem to disappear

Blue progress bar indicator:

Search pattern (invalid regular expression):

pageTitle: '([^']+)',\n.+)

Fixing the invalid regular expression problem does not make the problem go away:

This is not a new problem - this has been happening (intermittently) since shortly after the Search Editor was introduced.

Good catch. To clarify:

1. Open search editor and enable regex.
2. Search for pageTitle: '([^']+)',\n.+)
3. You get a loading animation that can't be stopped without closing the editor 🐛

Nice, thanks for the confirmation! ❤️

Just to be certain - I'm not sure that an invalid regular expression is the only way to trigger the endless search loading indicator.

If I see it reproduced with a different pattern, I will add a new comment.
