Description
Sometimes qutebrowser will crash when closing a page. Looking at the stack, I believe this crash is entirely inside QtWebEngine, not the python wrapper or the qutebrowser code. Here is the stack trace from the crash:

The relevant part starts at frame 17, where ~RenderFrameHostImpl calls document_associated_data_.reset(). This eventually calls ~DocumentAssociatedData (frame 12). This destroys a FederatedAuthRequestImpl instance, which has a valid auth_request_token_callback_. This causes a call to CompleteRequestWithError, which calls CompleteRequest, which calls render_frame_host().GetPage() (frame 7). GetPage tries to call document_associated_data_->owned_page(), but document_associated_data_ was reset in frame 17 and is now empty. This fails a libstdc++ assert, which crashes the program.
The final cause (using document_associated_data_ after it has been reset) is the same as QTBUG-136131, but the fix for that bug does not fix this issue, since this crash is not caused by audio logging.
