Any idea why this is only happening on OSX and Linux?

I suspect this is related to the function getting called multiple times due to subframes which probably aren't relevant to reader view and should be ignored. I think it should happen the same on every platform but perhaps a different ad network on sub-frames were served.

Dolske, can you find an owner for this?

AboutReaderListener.handleEvent() is filtering out subframe events, so that shouldn't be the cause here.

Alas I can't reproduce this with the URL in comment 0.
