OK many thanks! Looking at the link from @esmi to the other thread, seems like this is confirmed to be a false positive. Marking this resolved.
Well did some digging around and didn’t realize
add_theme_support( 'title-tag' );
had been added. So I’m just going to go with that and ditch manually adding wp_title to my header.
Still curious though about the esc_html question above in case some time in the future I do want to go ahead and filter on wp_title.
Thanks that’s what I’ll do.
