I looked at this. The problem is that the order of these 2 events is not deterministic:

1. Reader Mode button state change
2. webView:didFinishNavigation: (where we post AXScreenChanged)

I.e. most of the time, 2. happens after 1., so we can pass AXScreenChanged the parameter to say that reader mode is available (when it is, as learned from the Browser's ReaderMode helper's state). But sometimes 2. happens before 1., which makes it unreliable.

So currently this is not reliably possible without some more involved tracking of state and of this actual order.
