InstanceView: should change selected cloud if another cloud gets selected in the cloud viewer

the instance viewer has its own current cloud. It may be changed by a combobox on top of the table that shows the available instances to it.
It would be nice if the instance view would react to selection changes in the cloud viewer

how to reproduce:

1) select a cloud in the instance view
2) select a cloud in the cloud view

Result:
no change of the selected cloud in the instance view

Expected result:
the instance view reacts to the selection changes in the cloud viewer: You select another cloud in the cloud viewer and the instance view changes the selected cloud in its combo & the table shows the available instances in it.
