Subject: [PATCH] Autoplay detection update: ignore NotSupportedError
 exceptions (#12603)

* Ignore NotSupportedError exceptions in autoplay detection

This error is caused by a Content Security Policy that disables data: scheme for media URLs.
Before this PR, this error would cause autoplay to be disabled; now, if this error is raised it has the same effect as disabling autoplay detection.

* Remove warning that has been addressed by #11822
