In my application i am using ExtJS4. After upgrade from OpenLayers 2.12 to 2.13.1 i noticed that i am unable to resize windows (floating components) that are on top of the map, like the resize action was losing focus. When i drag the window outside map div the resizing works fine. The problem does not exist in 2.12. Also when i set the window to modal, the resize is working properly.
What may be causing such behaviour?
