Unable to reset deprecated setting in the UI

[rzhao271]

I have chat.tools.terminal.shellIntegrationTimeout set to 200 on Insiders. This is a deprecated setting.

1. Open the Settings editor.
2. Search "shell integration".
3. See a deprecation warning for chat.tools.terminal.shellIntegrationTimeout. Select the setting.
4. Click the gear icon on the top-left of the setting and select Reset Setting.
5. 🐛 The setting does not disappear from the editor. I have to clear the search query and search "shell integration" again for the setting to stop showing up.
