Chrome Version: 58.0.x.x
OS: Win, Linux, ChromeOS, Android

Pre-requisites: Run the following repro steps on a device with a touch screen

What steps will reproduce the problem?
(1) Start Chrome with --site-per-process or some equivalent flag
(2) Open a page with a cross-site iframe
(3) Touch a link in the sub-frame

What is the expected result?

The link should show a grey highlight, to alert the user to which target they've touched.

What happens instead?

The link becomes "active" (i.e. underline shows), but no highlight appears.

Please use labels and text to provide additional information.

This is not surprising since all the LinkHighlight code is controlled from WebViewImpl, but OOPIFs route events through WebFrameWidgetImpl.

Probably the controlling code should be factored out of WebViewImpl and placed somewhere accessible by both.
