Tests with controls showing are arbitrary

[danae404]

I have found three tests that test the position of a cue when the video controls are showing: media_height400_with_controls.html, media_with_controls.html, and enable_controls_reposition.html.

Because each browser has uniquely sized controls, the ref file cannot be accurate to all implementations. We should write these tests in a way that takes this into account. Perhaps we should consider a standard way to expose media controls during testing?

wpt pr for removing these tests: web-platform-tests/wpt#54340

At the next ttwg meeting I will bring up this issue and the issues that have been opened by Gary and Jer
