Able to reproduce the issue on mac 10.13.3 using the build without fix.

Verified the fix on Mac 10.13.3 using Chrome version #68.0.3419.0 as per the comment #0.
Attaching screen shot for reference.
Observed that menus from combo boxes match their parent's corner radius (4pt.png / 4dp).
Hence, the fix is working as expected. 
Adding the verified labels.

Thanks...!!
