Textbox: Editable textboxs not given focus on each trial and non editable boxes cleared

[RebeccaHirst]

This bug is sort of a 2 part bug.

First, an editable textbox is not given focus on every trial, it is on the first but after than you need to click on it to type.

Second, non editable textbox's are cleared following the first trial, so no text is shown.

Thanks for reporting! These might also make nice extensions to our textbox test to check against possible regression bugs. https://github.com/psychopy/psychojs_testing/tree/main/tests/wdio_textbox
