False positive: "a polarizing" flagged for being a mass noun but it's also an adjective in a list

> This dude went from a reasonable and cool European/Danish builder to a polarizing, cocky jerk

"A polarizing" on its own would indeed be some kind of error. But ***present participles*** are verbs in their -ing form which behave as adjectives. The same verb form can behave as a noun called a ***gerund*** and those are (almost?) always mass nouns.

In this case we can disambiguate that it's used as a present participle adjective by the fact that it's followed by a comma and then another adjective.

The issue does not name a source file, test, or entry point. Start by locating the mass-noun rule and its tests, then verify that the reported phrase is not flagged while comparable mass-noun uses remain covered.
