The play icon would ony show when the tab is in the background.

Hello,

I might have made a mistake when i described the bug. When the high contrast mode is disabled, the play icon(I am referring to the icon that suggests to the user that an interaction with the website/video is required to play the video) is displayed. I added a new screenshot that shows this difference.

That is website's control interface UI. It doesn't relate with us.
