Unable to open any quick pick from settings gear when release notes are open

[miguelsolorio]

Issue Type: Bug

When I have the release notes open I can't seem to open the any quick pick item (Command palette, color theme, file icons) as it is immediately closed. You can't see it in the GIF because it is sped up but it briefly flashes. This only repros on Windows and on release notes (doesn't happen on Welcome/Interactive playground pages).

Repro Steps:

1. Open Insiders
2. Open Release Notes (if not open)
3. Open any quick pick via the Settings gear (command palette, color/file icon theme)
4. 🐛 Quick pick does not open

cc @chrmarti @mattbierner unsure if this is related specifically to webviews

@mjbvz didn't we have a PR around this issue recently?

I think this is a duplicate of #68335

@mjbvz I'm not so sure, I think that one is about menus appearing where this issue is about the quick pick disappearing immediately. I think there is some weird interaction with the context menu restoring focus and the web view restoring focus to itself
