Predator and CL could not provide any possible suspects. Using the code search for the file, “PositionIterator.cpp” assigning to concern owner from GIT blame. Suspecting Commit# https://chromium.googlesource.com/chromium/src/+/3292bf38eb80cb87d701ce761dd36584318926ea Since the author is not chromium user, assigning it to the reviewer -- Assigning this issue to you as you were the reviewer. Could you please look into this issue and kindly reassign if it has nothing to do with the above changes. Thank You.
