Grid loses styles, missing data

I have confirmed this issue exists in versions 8.1.2, 8.1.1, 8.1.0.
The issue is not present in 8.0.6 ← this was the last 8.0.x version I was using before updating to 8.1.1

Just for fun (midight in PST), I will update to 8.1.3 to see if I can reproduce there too.
Edit: issue can be reproduced in 8.1.3
