This seems like a pure editing issue -- Oilpan is not relevant.

Predator and CL could not provide any possible suspects.

Using Code Search for the file, "inline_box_position.cc" suspecting the below Cl might have caused this issue

Suspect CL: https://chromium.googlesource.com/chromium/src/+/7aeceb41754fa0ff6d577a72463bbe5a6a978b8e

xiaochengh@ -- Could you please check whether this is caused with respect to your change, if not please help us in assigning it to the right owner.

Thanks!
