Inbox sometimes gets stuck loading infinitely when "unread only" is on

[Sjmarf]

This is still an issue in some cases

[Sjmarf]

Repro:

• Start with the "unread only" switched off
• Mark only one item as unread
• Toggle "unread only" on
• Observe that loading symbol gets stuck

I'm able to repro this again 🤔

[EricBAndrews]

Hmm, I was able to reproduce once but can't do it again. It was the same issue (loader got stuck in .idle), but I'm not sure how it got there 🤔

I'll put the "load more" button back in as a fallback for this--I don't love it as a band-aid but I'm stumped on this one. Maybe it'll go away with these planned changes

[Sjmarf]

I can consistently repro this using the steps in my comment above on both of my accounts 🤔

[EricBAndrews]

Yeah, I had it consistently until I stepped through in the debugger and now I can't get a single repro

[EricBAndrews]

Can you try to repro on eric/idle-debugging? I've added a bunch of test prints that may shed some light.

Band-aid fix is in place so I'm taking this off 2.0, but keeping it open because the root cause is still unknown
