Gregory raises a significant accessibility issue here.

But important information should not depend on and be conveyed via
presentation.

It may be better to address that point rather than trying to use the
presentation layer as a repair technique.

Content needs to be in the document not in the CSS. Text generated by
style sheets is not part of the document source. It is the same
premise as don't rely on color alone. Ensure that all information
conveyed with color or CSS is also available without color or CSS.

Using CSS in the draft to visually emphasize a phrase or word without
conveying that emphasis explicitly or semantically is an accessibility
failure.  One solution: Instead of using only a CSS red border  to
denote what is an "Issue" or "Big issue". Use plain old text
explicitly. Say "Issue: blah, blah, blah" or "Big issue: blah, blah,
blah". Then mark it up using the STRONG element.
