Where do you get straight's version of java-ts-mode?

Does it differ from lisp/progmodes/java-ts-mode.el
provided by Emacs core?

Do you use treesit.el from `straight' too?

I tried this with lisp/progmodes/java-ts-mode.el,
and can't reproduce the bug.

Very strange, there should be no difference between gui and tui.
