Describe the bug
In the Theme Builder, opening a color-section box will make it flicker between different sizes if your screen is not large (e.g., under 1300 px wide, or 580px tall). I've tried it in Firefox and Chrome, and only had it happen in Firefox.

Hi @danicholls ,
Thanks for reporting! Does it happen anymore? I can't get to reproduce, but I'm on a mac and so the platform that I am testing with may slightly differ.
Yep! Still happens. (Still only in FF.)
It is a little inconsistent, though. And sometimes resizing the height triggers it.
Thank you for the details. Will investigate.
Same, Firefox 69.0.2 (64-bit) in ubuntu

Fix will be available in "quasar" v1.3.1 (thanks to @ejez).
