When right clicking in a shader graph and trying to paste via the right mouse button, the context menu closes when paste is selected instead of pasting the text.

Repro:

1. Have some text on the clipboard
2. Create a project
3. Create a Lit Shader Graph
4. Open the shader graph
5. Right click on the background of the graph
6. In the search box, right-click and select "paste"

Result: Context menu closes

Expected: Text pasted

Environment: macOS and Windows (likely Linux as well)

Builds tested: 2023.3.0a12, 2023.3.0a11, 2023.2.0b15
