Post editor acting up in Android

Running Chrome 85 on Android 10, with Gboard 9.7 as my virtual keyboard.

The post editor tends to act up if I move the carat around a post - if I tap elsewhere in the text, the last word I was on is still underlined, and when I hit a key, it moves the carat back to that underlined word, and will either add what I started typing to the word, or delete the word altogether and replace it.

Moreover, lately when I hit enter, it adds a new line, but then dismisses the keyboard.

This is extremely annoying and makes writing posts via mobile a -Yoink!- nightmare.
