Inconsistent application of proxies inside Super Units

The proxy is not created for the first String input in these unit positions. The proxy is always forced on get item unit no matter its placement.

The proxy is also forced on the String input despite the angle not being sharp if I reposition the Get App Variable unit. So it's not clear when and why proxies appear or not in this particular case.

Here's an image with Get App Variable Unit repositioned and an Input that's made with hold ctrl+ drag & release method. The proxy now appears when it didn't before. The connection was made the same way in both cases.
