Requesting bisect to see when this issue was introduced. Note there is a reduced test case and more info at  http://crbug.com/571147  if helpful. I think they are the same issue so I'll dupe it to this.

 Issue 571147  has been merged into this issue.

====================================

This is a regression issue broken in M44, below mentioned is the bisect info:

CHANGELOG URL: https://chromium.googlesource.com/chromium/src/+log/1b8433765e4209f79f85d0de55497221d09cdb93..90afd1ba680b57e4ce812949a4d5accdb1309b42

Suspecting Commit: Unable to find the exact culprit from the above bisect link.

Could someone from Dev team please look into the issue, and please do assign it to the concerned owner.

Note: Issue not observed on MAC OS.

Thank you.

Performed both the examples mentioned in the description [http://www.deepika.com] and the .html file present in the issue -  http://crbug.com/571147  

Interesting bisect results. To be clear, the description in c#3 says it both can and can not be reproduced on Mac. I believe the first list is incorrect: This issue does *not* repro on Mac.

The bisect you provided would point to DirectWrite causing the issue on Windows, but that doesn't actually tell us when the issue was introduced in the codebase (Linux and Mac don't use DirectWrite). Can you also bisect on Linux?

@trchen: Could you please look into the issue, and if it has nothing to do with your changes and if possible please do assign it to the concerned owner.

Note: Issue not observed on Windows & MAC OS.

Thank you.

No longer reproduces.
