BTT frozen when Floating Webview not responding

Note: Before bug reporting, please make sure you have tried the latest (alpha) version of BetterTouchTool and that you have already tried to restart your system :-). If you encounter a crash, please attach a crash log from the macOS from the "User Diagnostic Reports" section.

Describe the bug
I have a floating webview which displays a remote control for a music app I'm running inside Parallels.
Sometimes the URL does not respond, and BTT never times out, so all BTT functionality is unavailable until either I get the endpoint to wake up or I force BTT to close.

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):
