Formulas ("math" markup) are not properly displayed in link previews. The formula is duplicated with "{\displaystyle }" shown around it, among other changes (like added underscores), powers are incorrectly shown as full numbers and bracketed letters are not shown.
Example: page – link preview
This is a response to CKoerner (WMF)'s reply on this topic.
@SUM1The updated code is on the beta cluster. Looking at some of the examples, things look much improved. I'll let you know when this reaches the actual wikis!
Possibly the same bug, not sure: page and link preview. The "O(log n) amortized time" text appears as "O amortized time" in the preview.
Perhaps this is a result of the "O" being a link immediately followed by parentheses?
Thanks for the report @Itamarcu! This issue is fixed as of March 5, 2018
@Itamarcu Yes, that would simply be a case of link previews removing brackets and their contents.
