Description

Looking at the filmstrip:

And the actual video.

My guess is that it picks up the change in the URL bar? I'm using Chrome 131 in the tests.

Research direction

Start by reproducing the visual-metrics timing issue on a Samsung A51 with Chrome 131, comparing the filmstrip with the recorded video and checking whether the URL bar is detected as the first change. Done means the first visual change reflects the page rather than browser UI, with the behavior verified against the reported scenario.
