Post Title header links no longer respect “Headings Typography” setting

Hi there,
I’m testing an upgrade to the Google Fonts plugin on my staging instance (old version: 3.0.13, new version: 3.0.17). With the upgrade, my list of posts is no longer displaying the correct font for Post Title links. Details about my setup and what is breaking below.

Setup: A list of posts each containing a Post Title element displayed as an H2, with a hyperlink contained to link to the post’s page.

Google Fonts settings:
“Headings Typography” – “WindSong”
“Title and H1 Typography” – “Spectral SC”
“H2”, “H3”, etc. – “Default Font”

Formerly, the H2 Post Titles respected the font I had selected for “Headings Typography” (Windsong). Now it is using the font I had selected for “Title and H1” (Spectral SC). I did notice some new CSS applied from your plugin

.wp-block-post-title, .wp-block-post-title a, .entry-title, .entry-title a, .post-title, .post-title a, .page-title, .entry-content h1, #content h1, .type-post h1, .type-page h1 {
    font-family: "Spectral SC";
    font-weight: 300;
}

which appears to be treating post-title a elements as h1 elements now.

Is this expected behavior?

P.S. Unfortunately I can’t give you access to my staging instance to see the issue, but I can link you to the production site so you can at least see my page layout. The lists of posts is on the home page: https://www.kosmeomag.com

Thanks!
