**Steps to replicate the issue** (include links if applicable):
* Navigate to a page which links to a page with a fraction in the lead, e.g. //[[https://en.wikipedia.org/wiki/JoJo's_Bizarre_Adventure|JoJo's Bizarre Adventure]]// links to //[[https://en.wikipedia.org/wiki/Diamond_Is_Unbreakable|Diamond Is Unbreakable]]//
* Hover over the link to the page with a fraction in the lead
**What happens?**:
The fraction "31⁄2" is displayed as "31⁄2"
**What should have happened instead?**:
It should be displayed as "31⁄2"
**Other information** (browser name/version, screenshots, etc.):
I believe this is due to the behaviour of the Unicode fraction slash character (U+2044), which (in most fonts) formats the number before it as a superscript and the number after it as a subscript. I'm not sure exactly where this happens, but it seems that the page itself displays it correctly by parsing it along the lines of `[3] [start fraction] [1] [fraction slash] [2] [end fraction]`, while the preview only parses it as `[3] [1] [fraction slash] [2]`.
