Good interface but could not get it to work outside the playground

Doesn't work properly on outlook browser app nor in gmail, which are precisely where I would like to use it. It messes up the rest of the text.

It can't access the chat field in roll20. As my only real use for it was to roll dice without typing a novel, or paying for a 'pro subscription', well...

Easy to use, but very buggy. I tried this extension in 3 different places, and it failed each time. On Facebook, it doesn't work. On reddit, it replaces text, but freezes the textbox. In Craft CMS, it replaces paragraphs of formatted text into plain text.
