Bug: Subscript and superscripts (sub/sup HTML tags) should make text smaller
Using HTML editor on developer mode I add some sub and sup HTML tags, for example to add an exponent. The text is moved up/down but with the same font size. Maybe this Wikipedia text is helpful: "the superscript *is about 60% of the original characters*, raised by about 44% above the baseline".

Workaround: take Unicode characters from utf8icons.com.
