It looks like the UI state won't be synchronized across multiple tabs, if you
open this subpage in multiple tabs.

But it looks like it wasn't synchronized in the old version too. Can you confirm
on your windows box? If it's no worse than before, it's fine.

I doesn't seem to be synced in the old settings page either. so i guess we're
good. phew...

We're "good". hehe. That being said, I think it's not that big of a deal.
