URL markdown in incident updates is breaking HTML container

[pridit]

Within the incident itself this appears as expected. However with updates:

This a [test](https://google.com) with a URL

Through inspect element I can observe the following:

<p><a href="#" class="list-group-item incident-update-item">This is a </a><a href="https://google.com">test</a> with a URL</p>
