TextAreaStopsProximity and GetImageUrlAtPoint are failing on iOS 11
iPhone devices. This is disabling them.

Re-enabled ContextMenuJsTest on device.

The test were probably failing because the page did not finish layout
after the load. Grabbing an HTML element forces layout and makes page
prepared for the testing.

This is a speculative fix, because I could not reproduce the failure
locally.
