Bug Description

When the before-close event is prevented using event.preventDefault(), the dialog does not close when attempting to set open = false.

Affected Component

ui5-dialog, ui5-popover, ui5-responsive-popover

Expected Behaviour

The dialog should still close as expected when the before-close event is prevented using event.preventDefault() and open = false is set programmatically.

Isolated Example
