Thank you, Eli, for looking into issue #32177. I was happy to hear that you were eventually able to reproduce the bug on your end.
I was able to reproduce the issue on my end with bidi-display-reordering set to a non-nil value of t, but it will take some time to come up with an emacs -Q recipe.
Although it is not often very that I need to inspect the undo-tree history file, setting bidi-display-reordering to a nil value of t gives a tremendous enhancement to movements within that buffer. Without setting bidi-display-reordering to nil, movements with arrow keys up/down and so forth is unbearably s-l-o-w. Occasionally, I have to inspect the desktop save file and that too has some very long lines where I think setting bidi-display-reordering may help. Here is a little snippet written by Noam Postavsky that produces a line matching the format of the undo-tree history file.
(require 'cl-lib)
(defun make-deep-object (depth)
(let ((obj 1))
(while (> (cl-decf depth) 0)
(setq obj (vector (list obj))))
obj))
(setq print-circle t)
(let ((buf (get-buffer-create "*test*")))
(with-current-buffer buf
(insert (prin1-to-string (make-deep-object 4964))))
(switch-to-buffer buf))
