@SenorGato apologies for missing the review request. I am wondering why we need a note on this event given that it's only one of many that aren't available in content scripts.
I'm not certain this is what we want to do. Content scripts have a limited set of APIs they are allowed to use. This same comment, if we addressed the issue this way, would need to be added to the majority of APIs.

@Josh-Cena as you can see, there are now two comments on this change querying how appropriate it is. We thank you for offering this suggestion, but on reflection, we shouldn't make it.
I think you've tagged the wrong person @rebloor (OP is @SenorGato) but I agree with your choice
