It has, though it has mainly been under the "breach of contract" approach and not under "copyright infringement" approach. See https://en.wikipedia.org/wiki/Open_source_license_litigation

Of course you're correct. I meant to say no GPL termination case, and I've corrected my comment to say that. By that I mean cases where the defendant had cured their breach of the GPL but continued exercising the rights the GPL would have given them but for the termination clause.
