Steps to reproduce:
1. Create a Content Type with two fields:

• ezstring: Name (category: Content)
• ezstring: Description (category: Metadata)
  2. Start creating a Content using the created Content Type
  3. Switch to "Metadata" category

Expected:
The "Metadata" category is highlighted as active

Actual:
The "Content" category is still highlighted as active

Note: I was only able to reproduce it using Behat (happens all the time), had no luck reproducing it locally so far
