I can see this really being more of a feature request.
The above is a screen shot of me testing boldface. One of the words above is bold, and for me, at least, the difference is subtle enough that, if I didn’t know one of the words was bold because I’d made it that way, I might completely miss it. The style sheet, according to the inspector, does define strong as a weight of 700, but that appears to only provide a slight thickening. I suspect the issue involves font loading, after rummaging around a bit (I’ve pasted a reference link below that tipped me off to what the problem might be).

I tried going into the inspector and editing the string to read
href=“https://fonts.googleapis.com/css2?family=Amatic+SC:wght@700&family=Open+Sans:wght@400;700&display=swap”
And that seemed to make it a bit more obvious.
