Blender Version
Broken: Probably forever (e.g. 3.0, 3.1)
Worked: N/A

Short description of error
If the output socket of a node is removed, the input socket it was connected to does not show a button to input a value. It acts like it's still connected.

Detailed replication

Go into the Shader Editor
Create the Voronoi Texture node and a Math node
Set the Voronoi Texture node to 4D, and plug its new W output into the Math node
Set the Voronoi Texture node to 3D. Observe that the input on the Math node still acts like it's connected
Click and drag from that input on the Math node. A bogus wire will appear from the Voronoi Texture node, coming from where the W output used to be.

You can then plug this wire into another socket. It will disappear again once you let go. If you set the Voronoi Texture node back to 4D, the wires will re-appear.

Video example:

XwBMq60aMI.mp4

Another example:

{F13079601, size=full}

In this case you can even save the file in this state where you can't see or edit the value of the node until you disconnect it.

Please add a written explanation of the bug -- a video alone is ambiguous, since we can't tell exactly what you're doing.

Okay, I've replicated the issue and updated the bug report with the details.

I can't think of any nodes that add and remove sockets in 2.8.0 -- if someone knows one, please try the above steps and see if the issue still exists in 2.8.0

Hi @lichtwerk , may be this is similar to #83269 (Noodles connected to vector math node may become invalid but remain connected after mode change)

Can you please check this? I think this can be merged into #83269

I think we should just be more aggressive when changing the node type and clean up the links.
