Autoplaying video

[s2156945]

Describe the bug In V3 the video elements do not behave the same as in V2

Expected behavior These should be the default, or at least possible options

• fill the "box"
• autoplay
• sound is off by default

Additional context If this is something which can be addressed in "porting" V2 dashboards to V3, i.e. these behaviours can be not default; e.g. different types:

• video - does not start automatically but when you do start it has sound
• video muted - as above but you need to turn on the sound if you want it
• video autoplay muted - current V2 behaviour
• video autoplay with sound - video autoplays with sound

I think this may be a quick change by setting autoplay in the HTML video element here
