I can also confirm this problem. Bug it goes a bit deeper than simply having problems in the published version.
If DomPdf has problems with many CSS things and currently other rendering problems related to variables.
I've found this here in @bsweeney's answer: https://github.com/dompdf/dompdf/issues/2828
That's why @flyke was able to render the 'color:red;' css without problems.
My theme was being loaded correctly by the rendering as well.
Thank you for the info lazzyvn.
1.5 worked without problems.
Thanks for the quick response and the quickfix.
Your merge request indeed fixed my issue!
I'm also having this problem.
Is there any easyfix while we wait on an update for the package?
It would be very much appreciated, since it is a very old issue that was supposedly fixed.
Thanks
