            Bug ID: 239031
           Summary: Removing x-webkit-wirelessvideoplaybackdisabled
                    attribute from video does not enable AirPlay
           Product: WebKit
           Version: Safari 15
          Hardware: Mac (Intel)
                OS: Unspecified

          Severity: Normal
          Priority: P2

Sample HTML illustrating the bug

A <video> with the attribute x-webkit-wirelessvideoplaybackdisabled cannot AirPlay. However, if the attribute is removed from the <video>, it still cannot AirPlay, and the property webkitWirelessVideoPlaybackDisabled remains true and cannot be set to false.

This bug with x-webkit-wirelessvideoplaybackdisabled is in contrast with the attribute disableremoteplayback, which also disables AirPlay, but AirPlay is successfully re-enabled when disableremoteplayback is removed from the <video>.

I've reproduced the x-webkit-wirelessvideoplaybackdisabled bug with Safari Version 15.4 (16613.1.17.1.13, 16613) and Safari Technology Preview Release 143 (Safari 15.4, WebKit 16614.1.7.7) on macOS 11.6.5.
