Thanks to your help, 3 months ago I have been able finally to understand
how persistence of window configurations/states should be implemented.
Also such implementation would not be possible earlier before other
improvements including window states and framesets were implemented.
So it seems now is the right time :)

Thanks, I pushed your patch to the branch.  I hope it would be possible
to do refactoring on top of your patch to avoid duplicating GUI code
like Eli asked.

There is no such problem on X, so I guess it's Windows-specific?

This looks like Windows-specific too.

The simplest recipe is this:

0. emacs -Q
1. M-x tab-bar-mode RET
2. Click on the plus sign to create a new tab
3. Click on the previous tab
4. Click on the close icon

0. emacs -Q
1. M-x global-tab-line-mode
2. Click on the plus sign and select a buffer to create a new tab
3. Click on the previous tab
4. Click on the close icon

This covers the basic parts of the user interface.
