This happens with a dsf > 1

Bug fix to add correct scale to the tab clip path

The clip path for tab is not being scaled based on the device scale
leading to incorrectly clipped tabs at HiDPI.

Unable to reproduce the issue on chrome version 66.0.3348.0 using windows 10 and Ubuntu 14.04. As ET team doesn't have "eve device" to check the issue, Hence adding label TE-NeedsTriageFromMTV and requesting someone from MTV to have a look into it for the verification of fix. 

Thanks!
