Predator and CL could not provide any possible suspects.

Using Code Search for the file, "SimplifiedBackwardsTextIterator.cpp" and observed some recent changes for the below file.

Suspect CL: https://chromium.googlesource.com/chromium/src/+/4bbd32a9e1f247a9491178f45d34c8c0d467b5c8%5E%21/third_party/WebKit/Source/core/editing/iterators/SimplifiedBackwardsTextIterator.cpp
