This prevents calls to nsPresContext::NotifyInvalidation from using a transaction id that has already been revoked.
Android does "repeat" transactions, where one EndTransaction call results in two transactions. The first updates the "critical" area of painted content (immediately visible). The second updates the rest of the display port.
What happens in the specific failing test that triggered this is the first transaction results in invalidations from layer tree invalidation. The second transaction nothing has changed, so it gets revoked. When EndTransaction returns to the nsDisplayList code and calls nsPresContext::NotifyInvalidation it uses the last transaction id stored on the layer manager. But this has already been revoked.
