Description:
As of now, every time you press the 文 button, a random <br> element is added to the HTML of the field after the furigana is generated. This diminishes the ability of the user to customize their own cards for no reason at all. The only solution for me is to manually enter the HTML of the field and remove the <br> every time I want to press that button, or for me to manually input the furigana in that field so I don't get the extra <br> as a combo.

This becomes more egregious because you actually edit the separators that are added to the pitch graph and the audio field in the generation settings for the addon.
