Loading a editor layout makes scene views impossible to reopen without restarting.

[badandbest]

Describe the bug

When you load a editor layout it closes the scene views. You're unable to open the scenes again until you restart the game.

To Reproduce

1. Open a scene.
2. Reset or load a layout (e.g "Matt's Layout").
3. All the scene views are closed and can't be reopened without a restart.

Expected behavior

• The closed scene should not be impossible to reopen.
• For "Reset Layout" I'd expect the scene views to be placed wherever the "Game" widget is instead of being closed.

Here is my review: The scene tabs aren't invisible anymore. 👍

But if you have more than one scene tab open the tabs are placed where the inspector is instead of the game view.
