Bug on minimize with Morphic backend

[Nyan11]

Hello,

There is a bug with Morphic backend when you minimize the spec window.

Reproduction

bug 1

In a playground:

BlElement new openInNewSpace

The click on minimize.

The window is destroyed.

bug 2

Open the bloc demo :

Clic on minimize:

The reopen it (by clicking on the bottom bar).

The space is gone.

Explication

In BlMorphicSpaceHostMorph >> initializeAnnouncement, when the morph that contains the space receive MorphDeleted it triggers BlMorphicEventHandler >> handleWindowClosed: who in turn closes the space.

I think MorphDeleted is send when the window is minimize because the morph is remove from the world.

My steps to reproduce:

1. Evaluate:

space := BlSpace new.
space useMorphicHost.
space show.

2. Move the mouse, and a corresponding icon will appear at the end of the windows bar (at bottom)
3. Evaluate 'space minimize'.
4. Move the mouse and the icon in the windows bar will dissapear.
