Small bug: Prefilled text does not dissapear

Hi, I experience quite often that when typing in the text field, the “message chat gpt” prefilled text does not dissapear. See screenshot. Not a big problem, but i find it bothersome enough to report it here, as i sometimes dont see what I type.

In my experience this happens always when typing japanese, & sometimes when typing english.
