<!--
This test suite performs scroll to text navigations to
find-range-from-text-directive-target.html and then checks the results, which are
communicated back from the target page via the WPT Stash server (see stash.py).
This structure is necessary because scroll to text security restrictions
specifically restrict the navigator from being able to observe the result of
the navigation, e.g. the target page cannot have a window opener.

// This test suite specifically exercises the "find a range from a text
