Formatting in the HTML editor changes the entire page
I just tried out the HTML editor for the first time. I have two editors that are part of a form. The first is for the message, the second for trade fair details. As the trade fair details do not change often, they are pre filled and formatted.
When changing the style to cursive for just one word in the message editor, the entire email changes to cursive (all form fields and other text). I also noticed, that the css sometimes changes for no apparent reason.
Did I mess up anything?
