Need method to reset bounds

What steps will reproduce the problem?
1. I initialize a map and add some markers with 'bounds': true
2. Then I remove the markers with $('#map_canvas').gmap('clear', 'markers') 
but keep the map to save initialization 
3. Then I add some other new markers with 'bounds': true
4. When I refresh the map $('#map_canvas').gmap( 'refresh' ); I get a map 
fitting both the new and old (removed) markers.

What is the expected output? What do you see instead?
I tried with a $('#map_canvas').gmap('clear', 'bounds') in step 2 but that left 
me with an unresponsive map.

What version of the product are you using? On what operating system?
3.0-rc1 used with jQuery Mobile on Android.

Please provide any additional information below.
