Can't load custom lists on GoToSocial

[kvibber]

I'm able to view custom lists on my Mastodon and Akkomane accounts, but not on GoToSocial. I checked the logs on my GTS instance, and every time I try to load a list from Whalebird, it's hitting the path:

/api/v1/timelines/list/01

(This is a 404, with an error logged that no SQL results were found.)

When I access the same site from Phanpy, it hits a path like this:

/api/v1/timelines/list/01HW1N3H6FWB0TGWQPA06V0V9A

And Phanpy is able to load the content successfully

So it looks like Whalebird is truncating or otherwise missing the list ID, which explains why it's getting a 404 asking for 01

I've seen this on both Linux and macOS with Whalebird 6.2.4 and GoToSocial 0.19.1.
