Text entry loses its focus and shifts left to before previous letter entered.
Whenever I go to website and try to log in, I type a letter and then type the next, which ends up to the left of the previous letter, and this continues to be the pattern. So I end up with gibberish that could be construed as secret code and would require a special detachment of scholarly sixth -graders to decipher. And it probably works in reverse if typing in Arabic, but that's only conjecture, I have not personally attempted that and lack the will for that research at this time.
