Button Element not updated if target ID contains colon

Created by: svenhaag

Bootstrap Version 4.0.0-alpha.6 and 3.3.7

Target ID = "collapse:Example" data-target = "data-target="#collapse\:Example"" aria-controls="collapse:Example"

Only the Target attributes get updated, not the button (toggle element) attributes. IDs with a colon exist especially in the JSF world.
