### Bug Description

Eg If I have MathJax turned on and have 'displayname' for a user set to: $$\beta \alpha \delta \varsigma \pi \rho$$

When I visit their profile page I see their name displayed as βαδςπρ in page <h1> tag but the browser <title> still shows as $$\beta \alpha \delta \varsigma \pi \rho$$ and makes things look broken

The MathJax is unable to update the <title> tag as it does it's magic with inserting <div> stuff.

But we can update the title tag with an approximation of what is wanted - eg for Greek letters they tend to exist in the font so we can scrape them from the page a apply them to the title.

For things like mathematical notations like square root we can't as they are made up by css tricks

So I'll add a bit of code to try and update the <title> tag so it looks less broken
