Hello @yankiara,
Thanks for the report.
We have fixed the issue with the responsive/pseudo selectors in 1.3.3.1.
As for Cwicly modals being overlayed by Gutenberg RichText popups, I currently believe this should be the default behaviour as they hold more specificity as to how they were triggered.
Please feel free to let me know if I might have missed something.
Moving to fixed.
Cheers,
