Steps to reproduce:

1. Open any Unity project that uses URP or HDRP
2. Open any Shader Graph asset
3. Click the right mouse button on empty space inside the shader graph editor
4. Click Create Node
5. Try to click any header to expand it

Expected (intuitive) result: clicking the header will expand it
Actual result: clicking the header results in an empty click and only the arrow expands the node

Note: clicking Enter with a header highlighted also does nothing

Reproducible with: 2020.3.46f1, 2022.2.12f1, 2023.1.0b10, 2023.2.0a9
