style sheet prevents Underlay from working?

I'm using TMP 2.1.4 on 2019.4.13f1.

I have a style sheet that changes color and font+material for a tag. However, the resultant text loses the underlay setting completely.

This happens whether I set the style using rich text or the TMP component's dropdown.

If using rich text, this even occurs if I set the TMP component's material and font to the exact same thing as the style indicates; it looks correct before the style tag, then loses the underlay.

Examples below, with blue color to differentiate styled text; this reproduces with the <color> tag removed.



If I just set Text Style to "bug", it looks like this:



Here's the entry in the style sheet:
