Hmm, this should work in some cases. Can you include a sample?

@Reporter: Could you please respond to comment#1 and comment#2. The latest chrome builds can be downloaded from the below link:
https://www.chromium.org/getting-involved/dev-channel

Thanks!
Sorry for my delayed response.

It seems that in version 55 this problem does not exist.
I found it on the release 52.0 but I've altered to another computer thus may not be able to verify it on the release 52.0 now.


I may still attach the test files.

Thank you for providing more feedback. Adding requester "vamshi.kommuri@techmahindra.com" to the cc list and removing "Needs-Feedback" label.

The latest Chrome stable version is M62, so you should test with that if you want to see if this is fixed for you. Are you manually held back onto an older Chrome version?

@ lesleydeng0: As per c#2 retry on recent version and update your observation.

Thanks!!
