Created attachment 477348 [details] Shows how the backdrop filter: blur; is disabled during the default view transition When using the view transition API, backdrop filters seem to be disabled while the transition is running. This is not the case in Chrome. Example page: https://openguessr.com The blur effect is disabled during the view transition. It should stay enabled, like in Google Chrome. Example video attached. Watch at 0.5x speed to make it more noticeable. Thanks!!

We're facing the same issue here. It is currently broken on both Firefox and Safari. Is Chrome the one not following the spec here or is this a bug from Safari/Firefox ?
