Selecting unplayable audio format disappears format selection widget

[triplingual]

Bug Description
Format choice widget disappears for audio if an unplayable format is chosen.

To Reproduce
Steps to reproduce the behavior:

1. Go to the IIIF Cookbook's AV Choice recipe preview
2. Scroll down to the Example section
3. Click on View in Ramp
4. In the Ramp public demo page that opens, click on the gear icon on the righthand side of the player
5. In the format selection widget, choose mpeg2

Expected behavior
Though I don't have specific behavior I expect from Ramp, I would say generally speaking that I would expect to get the message that the file cannot be played, while keeping the format selector widget so I could play a different format

Screenshots

Initial view of format selection widget

Format selection widget clicked

mpeg2 option clicked

Player bar showing error message and absent format selection widget

Desktop (please complete the following information):

• MacOS 14.1.2
• Firefox
• 115.8.0esr

Additional context

• If the cookbook recipe preview has gone away, the final version should eventually be at https://iiif.io/cookbook/0434-choice-av/recipe/0434-choice-av/
• After reaching the one-way dead end street once, I find that I have to clear my browser cache before I can get the format selection widget to return.

2 issues:

• control panel is unavailable when the player hits a stream it can't read
• the mpeg2 file should load and play

[joncameron]

Quality selector in Video.js handles the source change and this is outside of Ramp; will need to investigate to see what the cause of the error is.

This looks good for the error: the error message is readable, dismiss-able and much more clear to users. I'll create a new issue for the issue of the mpeg file from the IIIF cookbook example not playing.
