Beta 1 - Theme Editor Page Header vanishes

Okay, this is a little tricky to replicate but I think I got it. I think it's only a visual thing but it is irritating.

To reproduce:

• Use frontend theme editor
• Go to Logos
• Add a picture
• Don't save!
• Delete the picture
• Save the theme
• Header gone 🙂

Only adding a new logo and saving brings the header back. Only a refresh didn't work for me.
