How to update Fail Text in RED in TestRail

I wanted to update the Particular Text like Passed in Green and Failed in RED in TestRail.

It is a text area where we are entering the comment.. But looks like that Textarea will not render html code.

When I read that they are not supporting color for the text area..

You cannot use Markdown or HTML within a code block, which makes them a convenient way to show samples of Markdown or HTML syntax:

we can not change the HTML page but the only option is passing HTML code to the content.

Any possibility is there?
