Powers incorrectly rendered in "A short note about SHA-1"

[jubobs]

In A short note about SHA-1, numbers consisting of an integer raised to a power do not get rendered correctly. Namely,

• 2^80 gets rendered as 280,
• 10^24 gets rendered as 1024.

See the following screenshot (taken in Safari 8 0.7):

The rending is wrong in Firefox 40.0.3, as well. The <sup> tag is present, but the default browser styles which render subscripts and superscripts are overridden with the very first style in this spreadsheet:

html, body, div, span, applet, object, iframe, h1, h2, h3, h4, h5, h6, p, blockquote, pre, a, abbr, acronym, address, big, cite, code, .man-page p tt, .man-page .listingblock .content, del, dfn, em, img, ins, kbd, q, s, samp, small, strike, strong, sub, sup, tt, var, b, u, i, center, dl, dt, dd, ol, ul, li, fieldset, form, label, legend, table, caption, tbody, tfoot, thead, tr, th, td, article, aside, canvas, details, embed, figure, figcaption, footer, header, hgroup, menu, nav, output, ruby, section, summary, time, mark, audio, video

If you remove sub, sup, from this style, the superscripts and subscripts will be rendered properly.
