Yes, tab-line-mode resets the variable unconditionally:
(define-minor-mode tab-line-mode
"Toggle display of tab line in the windows displaying the current buffer."
:lighter nil
(setq tab-line-format (when tab-line-mode '(:eval (tab-line-format)))))
Perhaps that should be done only when the variable's value is nil?
(I've added Juri to the CCs.)
