What steps will reproduce the problem?
(1)Sign in to chrome or Browse as guest >> Navigate to chrome://settings/cupsPrinters page
(2)Click on Add Printer button >> In Add a nearby printer overlay, Click on ADD Manually link >> Enter details and click on ADD button
(3)In 'Select a printer manufacturer & model' overlay, Open Manufacturer/Model dropdown
(4) Now hit escape key and Observe.

Expected: Opened dropdown i.e; Manufacturer/Model dropdown should close on hitting escape key.
Actual: Instead, entire 'Select a printer manufacturer & model' overlay closes.

This is non regression issue as same behavior is seen from M59.

Note: In 'Add a printer manually' overlay,when protocol dropdown is open upon hitting escape key only drop down closes but not the entire overlay.

Attaching screen-cast for reference.
