V8.InvokeApiInterruptCallbacks means that V8 interrupted JavaScript execution at the request of the embedder (i.e. Blink or DevTools) and executed one or more callbacks provided along with that/those request(s).

I agree that it seems surprising that that would take so long and/or would happen frequently, but without more information I can't even guess as to what the cause might be. A reproducible example would be useful.
