Two line breaks in a row not working

I have a discourse instance running at, and for some reason posts with two line breaks in a row –

like this –

are being rendered with only one line break. I don’t have the markdown linebreak setting enabled. I haven’t found anything in the docs about this. Here’s an image to show what I mean.

To be clear, this happens both in in the preview to the right of the post and the actual post. Does anyone have an idea why this might be happening?

This appears to be due to custom CSS on the site.

If I visit Guía legal para inmobiliarias dañadas - Legal - Brigada then I see:

but if I disable custom CSS via Brigada then it appears properly:


Ahh, that makes sense. Thanks for that Michael!
