Closing the main window will leave the child window open

[captchaKing]

As in description. To reproduce open Gallery example, press Edit button, close main window.

There's usually two types of dialogs in modern GUI's. The ones that block parent's window event loop, and others don't. But all of them close with parent window.

Well,

• closing the main window will leave the child window open
• using the App → Quit menu will close the whole application

So I think the title is not accurate.

But yes, the parent window should probably be blocked while the child window is open. (Similar but slightly different, the base layer should be blocked when a pop-up is open: try resizing the gallery so that it's scrollable, opening the combobox, then scrolling the base layer with the mouse-wheel.)
