In the 5.0.6 release, when I load a post with fields in multiple tabs, the first one is no longer highlighted as active. It looks like all of the others until I click on it, and then it becomes active.
Confirmed, happening on mine after update as well. No functionality lost, just a minor css bug.
This is fixed as of 5.0.7
Sorry about this bug. Yep, it’s fixed in 5.0.7
