What is wrong with this piece of code when edited into the project? If nothing I would be happy to create a pull request.</p>

<p dir="auto">I understand <a class="user-mention notranslate" data-hovercard-type="user" data-hovercard-url="/users/cvrebert/hovercard" data-octo-click="hovercard-link-click" data-octo-dimensions="link_type:self" href="https://github.com/cvrebert">@cvrebert</a> might have had good reasons to lock the previous issue, I didn't understand them though. Would you be so kind to leave this one unlocked for me to give a reaction?</p>
<p dir="auto">Please consider removing the double border on justified link variation, like you have on multiple buttons in an input group, in the upcoming v3.1.0?</p>
