false positive: "heading" is not a mass noun

[chrisgrieser]

What got flagged?
Another heading to write. → heading is a mass noun. Harper: MassNouns

Why is this incorrect?
"Heading" is not a mass noun, you can count them: one heading, two headings, etc.

edit:
another false positive I stumbled upon: a setting

Ah this one I can fix right away. Heading is a mass noun like all other gerunds (I like heading home.) but of course that's not immediately obvious since it's way more common as a regular countable noun. This would just be due to me missing that when I was marking up nouns in the dictionary after adding the mass noun logic. I'll start a new dictionary curation PR.
