This test checks that <a href="https://bugs.webkit.org/show_bug.cgi?id=50657">bug 50568</a>
is fixed. It runs logSrc test as found in the test plugin which prints the src attribute
to stdout. If the bug is present, the logSrc attrbitute that triggers the test will be lost
and nothing will be displayed on screen. Upon success, this test should display the src
attribute.
