Gerrit plugin renders text far beyond screen border

When you open an issue with gerrit review pinned (e.g. QTBUG-59298) you can see, that some stuff that Gerrit Plugin is rendering in "Gerrit Reviews" pane is offset by a massive number of pixels.

Look at the horizontal scrollbar of your browser. Word "Gerrit" will be rendered in some insane length to the right.

It seems that there may be some bug in CSS. This span element that contains words "Gerrit Reviews" has "text-indent: 9999px"

I'm not a frontend expert, so this setting may make sense, but currently it causes problems in latest Firefox and Chrome.

Here's the upstream repository of the plugin project: https://github.com/MeetMe/jira-gerrit-plugin
