Right now it's fairly easy to encounter a situation when a tab coming
online wouldn't recognise that the connection can now be reestablished
for a while. This PR cleans up reconnection logic, reenables tests, and
makes sure we get online as robustly as possible.
### Change Type
- [x] `patch` — Bug fix
### Test Plan
1. Check that reconnection works as expected
- [x] End to end tests
