Do not use docked stack bounds unless all conditions are met.
TaskStack currently refers to the DockedStackDividerControler to
calculate the docked stack. However, only a partial set of the
conditions when this is valid were mirrored. The code now checks the
base condition (that we are dealing with the docked stack) and then
checks a null value before applying. Null is passed back from the
controller in the case all conditions are not met.
