rbpotter@ : 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.

Note:
1. This issue is also seen for 'Scale' text field in print preview window.
2. Able to reproduce issue in Canary build #72.0.3589.0
3. Unable to provide bisect using 'per-revision' script as it shows "We don't have enough builds.." error message for above regression range, hence provided suspect through 'Chromium bisect'. (Tried on other machines but still getting the same error)

Thank you..!
