Have you run gn in the component build with this?  The issue I'm worried about
is the blink component links gtest/gmock in in the component build, so if we
mark them test-only everything that depends on them will error out.  What
happens today if you violate a testonly rule?

Okay, it now should work in component mode because I turned off the flag for a
few target then. I filed a bug and marked those cases.
