Summary object-fit:fill doesn't work for a video element using a canvas stream srcObject

This was originally reported at crbug.com/1491624 for Chrome on iOS, but also reproduces in Safari 17.0 and STP 180 on macOS. Steps to reproduce: 1. Create a video element with object-fit: fill 2. Create a canvas element 3. Set the video element's srcObject to canvas.captureStream Expected outcome: The video fills the video element Actual outcome: The video only takes up part of the video element Visit https://pingxingyun.github.io/lark_sr_websdk_demos/test_object_fit/ and hit the play button to test this out. In Gecko and Blink, the video element is entirely blue, but in WebKit only the center portion is blue.
