Beta b13 is available in the first post.
* Fixed loading spinner in Firefox. It was too small, causing its rotation to be lopsided.
* Toast messages (popups in the bottom right) no longer overlap the playback controls as long as your playback controls fit on one line.
* Toast messages no longer appear in front of playback settings/speed/quality panels.
* Fixed dropdown boxes not opening when using a touchscreen with Microsoft Edge.
* In Microsoft browsers on Windows, the "Hold Visual" (rectangle that appears when long-pressing) no longer appears when operating the PTZ controls with touch.
* Fixed a bug where some compatibility warnings intended for the About panel might not get shown.
