Messages sometimes refuse to send on community-daily

Description

Environment: community-daily in Desktop App on Mac

Repro steps:
1) Favourite a channel by dragging it into the Favorites category
2) Attempt to send a message

Observed: The app gets in a state where it cannot send new messages. They appear sent for a moment before they become greyed out with a spinner displayed on the right side. These messages never send and never show the Retry/Cancel buttons. In the developer tool, you see repeated failed requests to /api/v4/preferences.
Expected: Messages send correctly. You don't see any requests to /api/v4/preferences.
