OS 15.5 iPhone backwards typing

Twice I have seen my iPhone start typing email messages with the text going right to left. The text stays left justified. It happened after I was using email on my phone, typed part of a message and then put my phone to sleep to finish later. When I unlocked the phone my previous email body was empty. And as I start typing, it goes backward. I have a captured video and attached a screenshot from it. Lmk if I can send the whole video.
