Broken Rewards panel for connected user: Rewards panel shows non-connected state

[Miyayes]

Rewards profile is connected to Uphold, and in a browser session where the Rewards panel was working fine. Suddenly it stopped working and broke.

Broken state involves:

• Shows Rewards panel spinning
• Then shows non-connected state panel
• The big toggle doesn't work (does nothing when clicked)
• Rewards-internals stops showing any Rewards profile data

Then rewards-internals showing no Rewards profile data:

STR

Intermittently reproducible.

I reproduced it by just going to different websites and channels, then clicking the Rewards panel really fast on each one. I was trying to go through many different creators to see their contribution banners, and then this suddenly happened.

A relaunch of the browser immediately fixed the problem.

I reproduced this again naturally in:

@Miyayes #30680 (in 1.58) may help with this, to the extent that the error state should fix itself without restart.
