Help improving my instagram macro

Hello

I would like to add a SVG icon to my macro I use for displaying a tiddler’s Instagram link.

\define instagram(title:"Instagram")
<$list filter="[all[current]has[instagram]]" emptyMessage="No Instagram link"><a href={{!!instagram}} class="tc-tiddlylink-external">{{$:/mk/icon/instagram.svg}} $title$</a></$list>
\end

This doesn’t seem to have the icon line up with the text, so I’m curious if other have solved this with a few extra CSS rules.
