Passing "dense={false}" to a custom Menu does not affect the dashboard MenuItem

[guilleironhack]

What you were expecting:
When creating a custom Menu with prop dense={false}, I expect all the menu elements not to have the dense properties

What happened instead:
The dense prop is not passed to the DashboardMenuItem and therefore it's not affected

Steps to reproduce:

• Add a Dashboard to an app
• Create a custom Menu with dense={false}
• Add the custom Menu to the Layout

Reproduced on the codesandbox. Thanks! This is weird though, it should have been fixed by #4241

Just noticed that #4241 was merged on next so this is fixed but will only be available in 3.2.0
