I regularly encounter the following issue: I’m editing a document using purely the keyboard, I use the / to bring up the suggestions menu to start an H2 or a Code Block, but instead of the top most option being selected the option is selected that my mouse happens to be hovering over (the cursor is completely invisible at this point by the way). Theoretically I can see that the wrong option is selected, but this totally wrecks my muscle memory. Typing /h2+enter should give me a Heading 2 style every time without fail, it shouldn’t matter where I left my mouse! Please, please, please add a little check to your mouse hover logic to wait for mouse movement before changing the selection! Or better yet don’t change the selection at all based on mouse hover (I think this is not good for usability and is an anti-pattern with no benefit).
