Sorry for leaving so many comments here, but I'd love for you to do one more thing, in the spirit of constantly improving the quality of this code base. Could you rewrite the commit() function to an async function that uses await rather than .then(...)? I know you didn't write that function, but it would be nice thing to do. :)

All good, my aim is to make it right 🙂

@mtsgrd thank you! I'll QA it again and then merge

Seems like a race condition here - textarea takes the height of the previous condition. I'll check if I can fix it 🙂
