<p><a href="https://github.com/samanpwbb" class="user-mention">@samanpwbb</a> when you made the changes you set </p>

<p>sup { vertical-align: text-top; }<br>
sub { vertical-align: text-bottom; }</p>

<p>this doesn't really give the text effects that would normally expected (actualy sub works more like a superscript with the above). I didn't find any actual use of either markup. So except if you have  stylistic/artistic reasons for the current values, would it be ok to change them?</p>
