The DocumentPictureInPicture JS API added in Chromium 116 is not implemented in
QtWebEngine. This results in createWindow() being called with a window type with
random value, which then causes qutebrowser to bail out:
Traceback (most recent call last):
File ".../qutebrowser/browser/webengine/webview.py", line 123, in createWindow
raise ValueError("Invalid wintype {}".format(debug_type))
ValueError: Invalid wintype 843995690
Until this is fixed in Qt, we pass an argument to Chromium to disable the API
entirely, so that web pages hopefully fall back to something else.
In the case of the new Google Huddle feature, this results in them still working
with an on-page overlay instead.
Thanks to Joshua Cold and Vivia for helping to debug this!
