[ShaderGraph] Only one entry in dropdown when choosing color channels for Swizzle node

Package: Shader Graph

-

How to reproduce:
1. Open the user's project
2. Open "New Shader Graph 1" in Shader Graph
3. Create a Swizzle node (Right-click -> Create Node -> Channel -> Swizzle)
4. Attach the color node's output as the input to the Swizzle node
5. Open the "Red Out" dropdown (or any other channel's output) of the Swizzle node
6. Observe available channels

Expected result: options "Red", "Green", "Blue" and "Alpha" are available in the dropdown
Actual result: only "Red" is available in the dropdown

Reproducible with: 2018.3.5f1, 2019.1.0b2, 2019.2.0a4
Could not test with: 2017.4 and older (no shader graph).

Reproducible with package versions: 2.01 to 5.3.1
Not reproducible package versions: 1.1.9 and older

Note: collapsing the node's preview or toggling the node's output (downward arrow at top right of the node when no output is attached) fixes the issue

  1. Resolution Note:

    This requires substantial improvements to our node changed events to propogate this information to the UI layer. This has been added to the feature backlog.

    This is actionable in the close future. Just make "Red", "Green", "Blue" and "Alpha" ALWAYS available in the dropdown menu for now, no major refactor needed. and If those components don't exist, then throw a warning or just default to 0 values.
    Shader Graph has been out of preview since 2019.1, 6 months ago and it's not acceptable to have something as essential to shader creation as swizzling be THIS broken and have a very hidden workaround (NOT a fix.) You can mitigate this easily. Thanks.
