Hi Steven,
your fix indeed working almost reliably, in that regard, that the predefined track-url and -properties remain visible at the bottom. In rare cases however, I still experience situations where predefined fields do moved out of sight.
Furthermore, I believe there is still an issue with the prompt fields, if they are getting used with something like "{font: Segoe MDL2 Assets; Regular; 13}x" in example. Doing so,
empty lines getting introduces unpredictably.
I don't want to bother any further with this topic.
A workaround for me now is, to avoid the prompt-fields and using Unicode symbols in the regular fields instead:

Thanks a lot for having a look into that.
Greetings
