Additional context

Not only Backspace.
When I start typing I see strange message "Hkgghbv".
Then all my inputed text become selected.
I can delete with Backspace my text but can't remove first letter.
When I drop selection and try to type again it paste all my previous text.

Text editing on mobile overall is not great. I think we need to fake a <form> field or something. Someone better at web stuff than me need to help out here!

With iPad virtual keyboard in browser works well!

On iOS (iPhone) backspace works. If you want to remove multiple characters, keeping backspace pressed does not work though. One has to press it multiple times.
