Right clicking in in the search box of a VFX or Shader Graph "Create Node" window closes the "Create Node" window

With the next context menus, right clicking in in the search box of a VFX or Shader Graph "Create Node" window closes the "Create Node" window. Previously it would show a context menu with "Cut/Copy/Paste" options.

Repro:

1. Create a project
2. Add a Shader Graph and VFX Graph
3. Open the graphs
4. In their background, right click and select "Create Node"
5. In the search box of the node, right click.

Result: "Create Node" window closes

Expected: Context menu with cut/copy/paste options

Environment: macOS and Windows (likely Linux as well)
