[Problem/Bug]: Save password prompt unresponsive

What happened?

After I enabled password auto filling, when the save password prompt appears, the whole webview2 window keeps unresponsive for a few seconds.

Importance

Important. My app's user experience is significantly compromised.

Repro steps

Use the official win32 getting start guide,
use this code to enable password auto save

auto settings_4 = settings.query<ICoreWebView2Settings4>();
settings_4->put_IsGeneralAutofillEnabled(true);
settings_4->put_IsPasswordAutosaveEnabled(true);

Go to google.com to login, and you should be able to observe the issue.

You can see my recording, the window can't even be dragged around when this happens.

It might be a regression, because I must have tested this feature in our app before and if it's this kind of unrepsonsive I will have disabled this feature.
