Summary Safari cache issue when using MSE

Reported 2023-12-13 02:27:37 PST
Steps to reproduce: 1) Open Safari and go to a page that uses Media Source Extensions to play a video. I've made a minimal repro page here: https://replit.com/@Jeroen-Veltmans/Safari-cache-mse-issue 2) Play the video like normal 3) Press the browser's 'previous page' button 4) Press the browser's 'next page' button 5) Notice how the player stalls What is the expected behavior? The player should play the video like normal. What is the actual behavior? The player stalls indefinitely. Checking the mediaSource, all sourceBuffers have been detached. The previous sourceBuffers still exist, but have an 'InvalidStateError: The object is in an invalid state' message for buffered. Extra notes: When opening the debugger and disabling cache, everything works like it should.
