I noticed that the line height of paragraphs are increased when they contained in MathML rendered formulas. This error for example occurs on the page https://de.wikibooks.org/wiki/Mathe_f%C3%BCr_Nicht-Freaks:_Cauchy-Kriterium_f%C3%BCr_Reihen#Herleitung_des_Cauchy-Kriteriums
I use Firefox 43.0 on Ubuntu.
Steps to reproduce the error:
- visit https://test2.wikipedia.org/wiki/Main_Page
- open a random page and save a long paragraph with inline formulas
Result:
