Adler video cuts off in UV on play

[benwbrum]

Several of the Stella Adler videos from HRC appear truncated when you try to play them.

• Example AA item page: https://annotatingadler.github.io/adler-project/the-seagull
• AA-created Manifest: https://annotatingadler.github.io/adler-project/the-seagull/manifest.json
• Original item on CONTENTdm: https://cdm15878.contentdm.oclc.org/digital/collection/p15878coll78/id/9
• Mirador playing CDM content with HRC-created manifest: https://norman.hrc.utexas.edu/mirador/p15878coll78/9
• HRC-created manifest: https://norman.hrc.utexas.edu/notDM/objectManifest/p15878coll78v3/9

Working hypothesis:
The UV div is set to be 350px high. The video itself is 540 pixels high, and when UV attempts to play it, it expands to 540, but the enclosing div does not expand.

Observations:

• We never include the height and width of video within the manifest when AA creates it. While this passes validation, it's really not semantically correct.
  • To try: add h/w to the manifest canvas to see if that affects UV
• We recently made changes to UV's CSS to get small audio controls to work. This involved a max height -- did that introduce a regression?

This also happens with a different, IA-hosted manifest: https://saamturner.github.io/betweenthelions/between-the-lions-ep-1

The next step is to adjust the height of UV with the IA-created manifest in isolation on codesandbox and bring it to the UV community.
