[BUG]Video Player Scrubber Loads Only in Half of Fullscreen Mode

[abankhele]

Describe the bug
When playing a video and maximizing the player, the timeline scrubber does not extend across the full width of the screen, instead loading in only half of the full-screen view. This issue occurs inconsistently—sometimes it appears when clicking the maximize button directly, but not always.

To Reproduce
Steps to reproduce the behavior, including the results:

1. Go to https://mco-staging.dlib.indiana.edu/media_objects/8336j0923
2. Click on the Play button in the center of the video.
3. Click on the maximize video player button.
4. Observe that the timeline scrubber is only loaded in half of the full-screen mode.

Expected behavior
The scrubber should extend across the entire width of the video player in full-screen mode.

Need some investigation - what is different in mco-staging than in avalon-dev that is causing this?

[Dananji]

I tried multiple video items in MCO-staging, and was not able to reproduce this issue in Chrome.

@elynema, @joncameron When you have the time, can you please check whether you can reproduce this? Thanks!

[elynema]

@Dananji I am not able to reproduce. @abankhele Can you share what version of Chrome you are running? Is the problem still recurring for you?

[abankhele]

Yes, the issue is still reproducible for me. I'm using Chrome Version 133.0.6943.127 (Official Build) (arm64)

[Dananji]

I updated Chrome to the mentioned version and tried the same item in the screencast in the issue description, and I am still not able to reproduce this issue.

[elynema]

I am using the mentioned version of Chrome with both the linked issue and the one in the video of the bug, both logged in and not logged in. I cannot replicate this bug on my macOS laptop.
