Summary Short HLS video with 'loop' attribute stutters at the beginning of 3rd loop

Under the following conditions, the video stutters: - Using <video> element with a src that links to an HLS manifest that has multiple renditions - Using the `loop` attribute - Short video (~30 seconds-ish) I tested this with multiple different sources. It doesn't appear to be an issue specific to one kind of video encoding or container format. This is a demonstration with 4 different video sources: Link: https://66vmt.csb.app/ Code: https://codesandbox.io/s/66vmt Debugging: - I tried "manually" looping the video by avoiding the `loop` attribute and instead running javascript that listens for the player 'ended' event and calls play(). This did not help - The bug doesn't seem to happen on older iPhone (couldn't get it to happen with iPhone 8) - I tried with a single-rendition HLS manifest, same bug This is my first time filing a Safari bug, is this the right place and is "Compositing" the correct component? It was the only component I found that mentioned video.
