Weird bug when backspacing

For some reason when I type...usually when editing a post. If I press enter to a skip a line or I add an effect like color or bolding, and I decide to backspace, it'll skip me to the end of the last sentence and start deleting from there. It's easy to retype the last 1-2 letters you accidentally deleted, but it gets annoying to constantly have to go back to whatever you were trying to delete. Just a minor annoyance really.

 

that happens to me too...
