This appears to be due to https://chromium.googlesource.com/chromium/src/+log/11be895df47331de2498478f18079696ae43529d%5E..11be895df47331de2498478f18079696ae43529d?pretty=fuller .

Yep. Marking as a dupe since there's already a bug from the original landing (reverted for other reasons.)

The size increase is expected, but I'm also tracking some mitigation CLs on that bug before I close it. Total size increase should be reduced by ~85% once they've landed.
