gui bug

[17600164659]

When I close all tabs and then reopen a scene tab, all the tabs below merge with the scene tab.

On the Web Version

Hello

This is actually the expected behavior or the editor.

If the tab group where the scene was placed is closed the tab will open in one of the existing tab groups.

Thanks in advance.

Tested several game engines, seems like nunuStudio is handling things differently:

1. Defold closes the tab but keeps an empty pane instead of merging
2. Godot closes the tab but opens a new empty scene tab immediately afterwards
3. GameMaker: Studio 1 doesn't use tabs but keeps an empty pane as well
4. GDevelop has a "home" tab which cannot be closed
5. microStudio shows an empty pane if no files are available

Accidentally closing the last tab leads to extra work in nunuStudio (restoring the layout after merge takes time).
Displaying an empty pane or preventing the tab from being closed would be helpful.
