All my titles are suddenly italics on the main reference list page within Paperpile. Just FYI.
The most likely explanation is an unclosed
<i> tag in the title of the paper at the top of your list. If that is not it, please contact us via the in-app chat or email firstname.lastname@example.org so that we can investigate further.
That was it! An i/ instead of a /i. Funny that it would propagate down the whole list like that, but I guess the list is just a web page after all. Thanks.
