Able to reproduce the issue on reported chrome version 65.0.3325.181 using windows 10.

As the issue seems to be fixed in latest chrome stable 66.0.3359.117 and on the latest beta 66.0.3359.106 hence requesting you to check the same on it and let us know if the issue still persists.

Attaching the screen shot for reference.
