was looking through the themes for a replacement and geode, pumkinpatch, united we stand, all have the same issue with text being cut off and the editor issue.
What I have noticed, if you go to a theme that does NOT have this issue when the page loads the text in the message box expands from where its being cut off to fill the
message box fully so there is no cut off. If you refresh the page you will see what I am trying to explain.
With the theme that has this issue the text does not expand past where its being cut off.
Not sure if that makes any sense
