Glad to see this has been captured; I've noticed it off and on and assumed it was some transient issue with state. Glad to see it is already well understood!

@brave/legacy_qa now that brave/brave-core#1867 has landed, we'll need to go through this issue with the latest 0.62.x build and verify that it's working and didn't cause any other obvious regressions. If things are looking good, we'll uplift to 0.61.x as per the discussion on the b-c triage meeting earlier in the week.
