If someone capitalises a character(see https://en.wikipedia.org/w/index.php?title=Founder_effect&diff=559607253&oldid=558757694 for example) the VisualEditor does not recognise it as an alteration to page text and rejects their edit.
Ed's fix on Friday corrected this; sorry for the bug. Now live in production.
It is actually being reported now on itwp: in order to do this http://it.wikipedia.org/w/index.php?title=DNasi_attivata_da_caspasi&diff=60101664&oldid=60089990 I had to delete the word and link it back again. Our guidelines about style require pages in that section to appear with the capital letter. I'll also add a link to https://bugzilla.wikimedia.org/show_bug.cgi?id=50452 which looks related. Thanks.
Filed 53210 for my last comment which I see it now, it was unrelated.
