BUG: overflow of form header

Hello 😁

After the 14.0 B release, the form headers got a bit more fancy 😁

However, when using a rgb or rgba input type, the popup color picker is cut off inside the header container:

I was going to start messing with CSS, but I don't want to possibly break something else, and since UNA knows their code best, what is fix?

This worked perfectly before 14 beta release, so something has changed between the two.

Thank you 😁
