Getting an extra span in my blot

[singpolyma]

In this simply blot I get an extra nested span inside with contenteditable="false" on it. This wouldn't be a problem except then this extra span also shows up in the getSemanitcHTML() output from quill which is quite annoying. Anyone know why I'm getting this extra child when I just call innerText here?

  static blotName = "mention";                                                                                                                                               
  static tagName = "span";
