The goal here is when users using braille input to type in values to a contenteditable we want to set the value to the corresponding element. The legacy behavior of setting innerText is problematic in some way and we plan to redesign the structure in a later timeframe.

This bug here is when the input contains some trailing whitespace, they would be ignored. We know in most cases the style won't change during editing but I can see your point. Do you have any suggestions on how to mutate the DOM in such case?
