Popover Before Hide

[1-0-1]

Feature request:

I have a need to programmatically prevent a popover from being closed such as an onBeforeHide method.

For example I need the user to enter a value on the popover and then click a button to confirm. I would like to intercept the hide of the popover if a value is required or they haven't clicked the button to prevent the popover from closing.

If no interaction with the popover is required or editing conditions are met, then the popover should close according to its triggers.
