when entering text in a form the cursor often jumps before the entered character

Samsung Galaxy S3 i747m Firefox 71 and beta(good example, the 7 was placed before the 1, and I had to reposition the cursor) Swype 1.3.5.x (tried with stock aosp keyboard, same result) The cursor often jumps back one position while entering text into a web form. this makes entering numbers and passwords near Impossible. I can reproduce this error regardless of keyboard.
