Subject: bug#71386: 29.1; Frame is auto-deleted even when it has multiple tabs 
Date: Thu, 06 Jun 2024 00:44:28 +0100

If I open a frame with multiple tabs, and one of the tabs has a dedicated window, then kill the buffer with the dedicated window, the frame is deleted along with its tabs.

I understand that this is the documented behaviour, however my expectation is that the tab should be deleted but the frame should stay when other tabs are available, similar to how the frame is not deleted if other windows are visible.

The following code illustrates the issue:

,----
| (with-selected-frame (make-frame)
|     (tab-bar-mode)
|     (switch-to-buffer (generate-new-buffer "test"))
|     (tab-bar-new-tab)
|     (switch-to-buffer (generate-new-buffer "test2"))
|     (set-window-dedicated-p (selected-window) t)
|     ;;(kill-buffer)  ;; Kill buffer manually to see the issue
| )
`----

I am unable to test this on Emacs 30, but I checked the source code and `window--delete` in `window.el`, which is the function that I think should be changed, seems to do the same as in Emacs 29.1.
