Line height is ignored on font

I cannot change the line height on any font for the site; it’s extremely annoying. No matter what I put here it’s ignored, any ideas?

Please include your site’s Read-Only Share Link with your question.
A read-only link allows the community to view your project without making any edits to it and help diagnose your issue or provide feedback.

If your project has custom code or layout issues on the published site, please share that URL/URI as well.

I’d rather not if that’s ok; site isn’t public yet.

Then debugging your issue is near impossible for the rest of us. I suggest using browser dev tools myself to isolate the issue.
