Theme editor error tooltip cutoff
Theme editor error tooltip cutoff

closes: CNVS-22232

Test Plan:

- Go to Theme Editor
- In hex code box do something like "#0" and cause the red error box to appear
- Add something longer in there ("#92837498798324") to make it a longer
error string
- These should now be working xbrowser without cutting off the box
