Tokenizer fails to tokenize font property correctly if line-height is using a custom property. Example of CSS that is not tokenized correctly:

html { font: 1em/var(--line-height); }

Tokenizer seems to think that 1em/var is a function.

I created a failing test for this here: lauriii@8708558

This trickles down to https://github.com/shellscape/postcss-values-parser. I also created a failing test for that lauriii/postcss-values-parser@d0bbbbc.

This finally trickles down to https://github.com/postcss/postcss-custom-properties. I did also create a failing test for that: lauriii/postcss-custom-properties@6de537e.
