Our customer wants to print a multi-page document using firefox. We already knew the Firefox is not able to render html's fieldset element across multiple pages for years. reported 10 yrs ago: https://bugzilla.mozilla.org/show_bug.cgi?id=471015 But we now found out that this also applies to flex-boxes. Recentish issue here (8 mths): https://bugzilla.mozilla.org/show_bug.cgi?id=1414253 I also found an overarching issue that is marked as fixed from 17 years ago about overflow styles, but surely isn't fixing it for flexboxes: https://bugzilla.mozilla.org/show_bug.cgi?id=129941 Best thread I've found about it so far is here: https://stackoverflow.com/questions/26036663/page-break-after-not-working-in-flexboxes So Mozilla people, is this on your radar? Or should we all move to server-side pdf generators instead? Hope on one of you finds the time to pick this up. Cheers O and by the way, I prepared supporting imagery but the upload doesn't seem to work..?!
