It seems the test has been flaky at latest since Feb 28.  Probably it's getting slower and slower.
This might be GC-related issue.  The test calls gc() multiple times.

Have htmlcollection-reachable.html force the one GC needed.

Calling window.gc() slows down test running times, and is
preferably avoided unless needed to verify behavior across
a GC.

For htmlcollection-reachable.html, we only need the
one GC to determine liveness of custom properties for
various platform objects across a garbage collection.
