[panopto] Videos are clipped when horizontally longer than the display

[saschanaz]

Describe the bug

Panopto incorrectly shows 16:9 video way too big on 3:2 display.

(I'm definitely using a 21:9 monitor connected to my Surface Pro but the laptop display is still 3:2.)

To Reproduce

1. Access https://mozilla.hosted.panopto.com/Panopto/Pages/Viewer.aspx?id=ae2caf59-9253-4ee3-b4cb-ac410123959d
2. Make the video fullscreen

Expected behavior
What do you think should happen instead?

Browser and OS

Additional info

The same doesn't happen on YouTube.

Think I'm gonna (eventually) close this with 'wontfix,' blacklist the site by default and call it a day because:

• I really don't like the way things are coded
• It's not like anyone uses this site
• And for the handful of users that do, unnecessary black bars prolly don't happen a lot given they seem to mostly host talks and stuff.

Notes to self:

• Likely broken by width: initial !important bit of CSS that is always enforced (which needs to be there because twitch and IIRC Hulu.
• Caused by the fact we don't do height: initial !important, because that breaks a few other sites (having both width and height on initial: important may result in videos the size of a postage stamp).
• Or maybe we could decide which of the two (width, height) we set to initial !important based on player aspect ratio. Prelimiary toying with inspector shows promising results

Yeah, I just switched to enable it only for allowlisted sites so that it won't affect random sites. It's not that every service has broken videos anyway.

Turns out this was not just an issue on this site — it was also happening on Netflix and ... on a lot of sites, actually.

Figured why. Things work now, unless you try to do 'fit height' ... in which case, they don't always work quite (at least as far as Netflix is concerned).
