737357 - Show play button animation also for smaller videos

Based on bug #666306, comment #68

The specs say that the play button animation should show for videos having the width greater than 128px or height greater than 100px (128px - 28px for the control bar) (bug #666306 comment #65). Currently, the animation shows only for larger videos (from 276x155). 
It would look better if the animation also worked for smaller videos, at least for those having height >128px (not necessary for h>100px as it was initially intended), since the video looks large enough to show it.

I have been using the following test page to reconfirm this issue: https://tekeye.uk/html/html5-video-test-page
Test results:

• Video with 216x120 resolution does not show the play button image on the video before it starts playing and it does not show an animation when the video starts.
• All the other videos lack the width and height attributes in the HTML, but are visually bigger players in the webpage. All those players show a play icon on the video before it was played and it shows an animation of the play icon being enlarged while opacity decreases until it disappears.

In conclusion, this issue still reproduces Nightly v125.0a1 and ESR v115.9.0esr on Win10 and MacOS11.
