Constrained create issue dialog does not update behaviour context id

Opening multiple constrained issue dialog on the same issue page does not refresh the behavior context id obtained using getBehaviourContextId().

Steps to reproduce:

• Create two constrained issue dialogs
• Create a behavior to check the getBehaviourContextId() value
• Open the first constrained dialog, the getBehaviourContextId() value is correct
• Press the "Cancel" button on the dialog and open the second constrained dialog
• Here the value of the getBehaviourContextId() method is wrong, the value is still the one from the first dialog

Expected result

The getBehaviourContextId() method returns the correct value each time a constrained issue dialog is opened

Actual result

The getBehaviourContextId() method returns the value of the first constrained issue dialog opened
