Beautification does not start

[Drachenbauer]

Hello
I have problems getting it to work on Firefox 118.0.2
At first i can use the controls on the right side, but after i loaded a js file into it, it´s contend overlapps with the controls and blocks any clicks on them.
I´m getting a hand-pointer, when i´m at the very top of the "Beautify Code"-button, but clicking still has no effect and the keycode, that is also displayed on the button, has also no effect.
What is the problem with this on firefox?

Not sure what the problem is here. Needs more analysis.
