   656         This field tracks the location bar state. The value that the user typed

   657         in to the location bar may not be changed while this field is zero.

   658         However invoking a load will temporarily increase this field to allow

   659         the location bar to be updated to the new URL.

   661         Case 1: Anchor scroll

   662           The user appends the anchor to the URL. This sets the location bar

   663           into typed state, and disables changes to the location bar. The user

   664           then requests the scroll. loadURIWithFlags temporarily increases the

   665           flag by 1 so that the anchor scroll's location change resets the

   666           location bar state.

   668         Case 2: Interrupted load

   669           The user types in and submits the URL. This triggers an asynchronous

   670           network load which increases the flag by 2. (The temporary increase

   671           from loadURIWithFlags is not noticeable in this case.) When the load

   672           is interrupted the flag returns to zero, and the location bar stays

   673           in typed state.

   675         Case 3: New load

   676           This works like case 2, but as the load is not interrupted the

   677           location changes while the flag is still 2 thus resetting the

   678           location bar state.

   680         Case 4: Corrected load

   681           This is a combination of case 2 and case 3, except that the original

   682           load is interrupted by the new load. Normally cancelling and starting

   683           a new load would reset the flag to 0 and then increase it to 2 again.

   684           However both actions occur as a consequence of the loadURIWithFlags

   685           invocation, which adds its temporary increase in to the mix. Since

   686           the new URL would have been typed in the flag would have been reset

   687           before loadURIWithFlags incremented it. The interruption resets the

   688           flag to 0 and increases it to 2. Although loadURIWithFlags will

   689           decrement the flag it remains at 1 thus allowing the location bar

   690           state to be reset when the new load changes the location.

   691           This case also applies when loading into a new browser, as this

   692           interrupts the default load of about:blank.
