Headings not recognized by SEO

I happened to notice that the spectra heading block is not recognized by SEO plugins (Rankmath in my case) as headings. I have no idea if google sees them properly or not.

I like these blocks better than default since I can include text (wish I could set it inline rather than just above or below) and prefer the aesthetic over the SEO but this bug(?) might impact others needing to prioritize function.
