Hi, Juri,

[The patch probably needs to be rebased on master but I was able to apply
it by hand, I think.]

The conditions it's testing for are not ones that exist in my case.

The conditions are:

I'm not using the display actions in my configuration and I don't invoke
the tab-bar functions that use it.

I have two tabs on a newly opened frame.  Both tabs have only one window.
If I'm on tab 2, and I eval (kill-buffer), the frame disappears.

From inside window-deletable-p: tab-bar-mode=t #tabs=2 quit-restore
parameter=nil window-dedicated-p=nil frame-root-window=t

HTH (hope that helps and happy to help),

-Stephane
