This is a bit of a silly bug, but you can fix this by copying two whole blocks of text that contain LaTeX in which case the content gets properly copy-paste (and then you can just delete one of them). It’s a silly bug in the MathJax framework we are using, that has to do with how copy-pasting of multiple blocks is handled differently than copy pasting of individual lines.

Thank you, that’s very helpful.
