[4.5] Buttons in Viewport doesn't work

I have been using 4.5 from repo.

This was last change I pulled:

[INTEGRATE] Change 2307012 by Matt.Kuhlenschmidt@matt_kuhlenschmidt_main on 2014/09/23 11:59:52

	Fix UMG widgets clipping outside of viewports

[CL 2307075 by Ben Marsh in 4.5 branch]

Reproduction is very simple. Just try to click on any of the buttons which are in viewport. Perspective, Lit, Show, Arrow, snapping modes etc. You will just click trough and select whatever is in background.

Hah, thanks for letting us know. A fix is pending.
