I am going to mark expectations as pass fail while this pends investigation.

309490@main rebaselined this test to reflect progressions from the image map id-matching fix.
                                                                                                                                                                                                          
Before the commit, all 8 subtests consistently FAILed (image maps weren't resolving, so all events targeted img#img1 instead of area#area1-1). The expected file matched this stable all-FAIL output.
                                                                                                                                                                                                          
After the commit, subtests 1, 2 now consistently PASS . However, subtests 3 ("area is resized"), 5 ("usemap is modified"), and 7 ("new area is available") are non-deterministic The rebaseline assumed 3=FAIL, 5=PASS, 7=PASS, but all three flake in both directions.
