function LayoutBuilderDisableInteractionsTest::assertContextualLinkRetainsMouseup

Makes sure contextual links respond to mouseup event.

Disabling interactive elements includes preventing defaults on the mouseup event for links. However, this should not happen with contextual links. This is confirmed by clicking a contextual link then moving the mouse pointer. If mouseup is working properly, the draggable element will not be moved by the pointer moving.
