Hi,
I have checked this now: sorry, but that's a new Firefox bug and that would need to get fixed from Firefox side.
The inner iframe itself wrongly captures the input... might be related to the CSS 3D transforms...
Best regards,
Klaus
Thanks Klaus for taking the time to check this.
We'll monitor Firefox new releases (I think that the current official release is 99.0.1 (Windows, 64 bit)) and update the thread accordingly.
Ciao,
Guido
