Regression A/V problem: multiple media files in one canvas

Current behavior:
We added a link to the UV in the IIIF Cookbook for recipe # 64, Opera in One Canvas. This recipe demonstrates the ability to use one single canvas for multiple A/V files, each using a fragment of the time. Part of approving the process was to demo it, which was done using UV (see recording on minute 38:58).

The link demonstrated in the video no longer works. UV does not play the second file.

Expected behavior:
We expected the UV link in the recipe mentioned above to still work.

Steps to reproduce:
Go to the recipe, and click on the link View in Universal Viewer and try to navigate to Atto Secondo.

Has this been fixed? I was just testing the cookbook UV link and the table of contents seems to be working :-).

[mcwhitaker]

Yes, but now the video doesn't show on the viewer? The playhead moves and is correctly showing two files. @glenrobson is the video playing correctly for you?

[glenrobson]

Ah no... you're right I got too carried away with the playhead moving and didn't click play...

Hi @edsilv, the commit above suggests that this issue was fixed, but it still seems to be failing in v3 and v4 of UV. Is this a known issue, or something that has popped back up?

[edsilv]

@markpbaggett This appears to be working in 4.0.1? https://www.universalviewer.dev/#?c=&m=&cv=&xywh=-2494%2C-197%2C7556%2C3936&rid=%5Bobject%20Object%5D&t=11.57800006866455

However, @stephenwf there's a scaling issue with the video where it's overlapping the share and download buttons.

[stephenwf]

Looks like that might be unrelated to video. Fixed inline by removing the style="height: 570px" which doesn't take into account the 20px of padding in the parent on 2 inner elements (.views and .resourcesView > ul)

@edsilv and @stephenwf, hmmmm. I'm still getting the same error in v4.0.1 with the manifest in the recipe:

https://iiif.io/api/cookbook/recipe/0064-opera-one-canvas/manifest.json

Everything is good until we get to the second annotation on the Canvas at 3971.24. The duration keeps going in the viewer, but the second annotation doesn't appear.

I also threw together a quick gist of my own that has the same problem:

All is good until we get to the second annotation.

I'm also still seeing the same problem as @markpbaggett with v4.0.1:

related? https://github.com/pulibrary/figgy/pull/2524/files

[markpbaggett]

@edsilv, I'm not sure if it's related or not, but maybe. It's hard for me to tell what that Figgy fix was doing.

Some other things I noticed: UV seems to be fetching the painting annotation on the second canvas just fine. It shows up on the network tab of a page with the viewer but it doesn't paint it in UV.

Apologies for not providing better feedback or responding sooner.
