Hey guys,
I cant reply to the original ticket (https://theme.co/apex/forum/t/print-css-vs-firefox/33973), cause its already closed. So here my answer. The problem described in the link above, is definitely a theme x/pro bug and can be fixed for now with this additional css:
@media print {
.x-root { display: initial; }
}
Please fix this in a future release.
Thank you!
Best,
Robert
