Bug 139330 – AX: I cannot activate links on the mobile version of news.google.com

• Component: Accessibility
• Status: RESOLVED FIXED

[chris fleizach]

If I visit news.google.com on iPhone with VOT enabled, the mobile version by default appears. If I touch Top Stories, swipe once to the right, then double tap to activate the first top story link, nothing ahppens. Turn off VO and do the same, you’ll be brought to the proper location, which may mean a new tab.

This is because news.google only listens for touch events and ignores all other kinds of clicks.
we need to simulate a touch event

Would be nice to pull this enum translation out into a small separate function.

Is this relevant?

You have some commented-out code here.
