Revert of Disable the image notification property on MacOS (patchset #3 id:40001 of https://codereview.chromium.org/2803303002/ )

Reason for revert:
This broke a bunch of webkit tests.

https://uberchromegw.corp.google.com/i/chromium.webkit/builders/WebKit%20Mac10.10/builds/32377

I think you need to update the test results when you remove the feature.

No worries. I blame the CQ, really. There's no reason that it should have
skipped webkit tests...
