Thanks for the clear recipe.  With it, I'm also seeing errors (in both
Emacs 27 and 28):

Debugger entered--Lisp error: (error "internal--syntax-propertize did not move syntax-pr...")
  backward-prefix-chars()
  back-to-indentation()
  current-left-margin()
  move-to-left-margin(nil t)
  #f(compiled-function () #<bytecode 0x155c01f42651>)()
  self-insert-command(1)
  newline(nil 1)
  funcall-interactively(newline nil 1)
  call-interactively(newline nil nil)

But I'm not seeing the "binding depth" one.
