I have used the <sup></sup> HTML tags for exponentials and footnote numbers in SE posts for a few years now, and it worked as expected. For example, to render x^y, one can write:

x<sup>y</sup>

However, the past week (past few days?) I have noticed that they have ceased to work. They make the number smaller, but the raising of the number above the base line no longer happens:

<sup> tag not working

Unfortunately, for obvious reasons, can not get a screen shot of how it used to look.

Why is this? Has there been a recent background change? Happens in Chrome and Opera (I've not tried anything else).

This might possibly help developers to fix things a bit faster, please look at the bottom-right corner of this image, the sup selector has the vertical-align property valued tobaseline. Unchecking the box in Firefox's developer tools brings back things to normal.
