Context menu children change color when hovered if opened in the projects window

The new context menus can sometimes exhibit an odd change in color when mousing over a sub-menu if the context menu was opened in the Project window.

Repro:

1. Create a URP project
2. In the project window, right click and select "Create" -> "Shader Graph"
3. *Note that the sub menu isn't a leaf, but is still a different color.
4. Now hover over the "URP" item in the sub menu to expand another sub menu.

Result: When the "URP" item is hovered over and the next child is opened, the current context menu changes color.

Expected: Consistent colorization

Platform: macOS and Windows. Probably Linux as well.
