Subject: bug#37941: 26.3.50; Wrong behavior when reverting a tabulated-list-mode buffer with truncated lines

When I revert a regular tabulated-list-mode buffer, the point stays the
same, and the displayed buffer boundaries remain the same as well.
However, when the entries in tabulated-list-entries contain strings that
are too long and will be truncated, reverting such buffer will scroll
the screen by one line.
To see this behavior, evaluate in emacs -Q, then type g:
(with-current-buffer (generate-new-buffer "test")
(require 'cl-lib)
(tabulated-list-mode)
(setq tabulated-list-format [("No." 5) ("Message" 10)])
(let ((message (make-string 100 ?a)))
(setq tabulated-list-entries
(cl-loop for i from 1 to 100
collect `(,i [,(number-to-string i) ,message]))))
(tabulated-list-init-header)
(revert-buffer)
(forward-line 50)
(pop-to-buffer (current-buffer))
(recenter))
You can also see that if the lines are not truncated, the behavior is
correct.
