 # Tests for XUL <image> with 'object-fit' & 'object-position':
 # These tests should be very similar to tests in our w3c-css/submitted/images3
 # reftest directory. They live here because they use XUL, and it
 # wouldn't be fair of us to make a W3C testsuite implicitly depend on XUL.
-# NOTE: These are marked "skip-if(Mulet)" for now, because they seem to impact
-# the reftest-chunking in a way that makes later tests fail (likely through no
-# fault of these tests here, aside from their impact on chunking). See:
-#   https://bugzilla.mozilla.org/show_bug.cgi?id=1170052#c25
-# And they're skipped on B2G Emulator (like everything else in this file)
-# because XUL reftests trigger error pages on that platform.
