Straighten Connection shortcut doesn't work after removing array element pin

If an array element is removed from a make array node, using the shortcut for Straighten Connections has no effect until after the Actions menu is opened via right-click then closed.

1. Open UE4 Editor (any project)
2. Set up Straighten Connection shortcut in Editor Preferences->General->Keyboard Shortcuts
3. Add blueprint based on Actor
4. Add Make Array node and Print String node
5. Wire Print String into Begin Play (make sure the wire is not straight)
6. In the Make Array node, right click [0] and select Remove Array Element Pin
7. Select both BeginPlay and Print String nodes
8. Press your connection shortcut key

Result:
Wire connecting BeginPlay and PrintString does not straighten until after Actions menu is opened/closed

Expected:
Wires can be straightened after removing array element pins.
