BUG on Delay+visibility from UMG Event construct

Using a “delay” node on “Event Construct” on one UMG Event graph to change the visibility from “Hit test invisible” to “visible” block all interaction but if you build the application and launch outside the editor, that works. If you don’t use the delay node and just add 2 nodes to change the visiblity from “Hit test invisible” to “visible”, all interaction is not blocked.
Hope a fix can be added.

This is fixed in 4.8
