When the local API is selected, you can only support these playlists if backend fallback is enabled, please add the relevant checks. Feel free to take inspiration from how we hide the popular button in the side bar.

Will wait for #4597 to be merged before adding rest of changes (basically the playlist view loads but the playlist on the watch page still has some issues)

[ChunkyProgrammer]

Looks like the share menu on the watch page doesn't work correctly. For the YouTube links it includes the playlist ID, even though it it won't work as it's an Invidious playlist and for the Invidious ones it uses the current instance instead of the playlist's instance.

I guess we should just remove the playlist id in this case?

[ChunkyProgrammer]

I will be setting this to WIP as I'd like to revisit this once the piped PR is merged (I'd also like to add support for piped playlists)
