Beginning with Safari 15 on iOS we have observed setting a video element with a src="blob://url.mp4" results in the blob data being reloaded endlessly and a large build up of memory.
Load the following codepen on Safari 15.0 or 15.1 on iOS or iPadOS
https://codepen.io/eoinlandy/pen/ZEJJyqy
Observe in the network panel of dev tools the blob url is loaded repeatedly until Safari reloads the page due to excessive memory usage.
This does not affect Safari on macOS desktop.
