Mypy 1.16.0 flags errors here: lib/matplotlib/_mathtext.py:2531: error: "Node" has no attribute "width" [attr-defined] lib/matplotlib/_mathtext.py:2608: error: List item 0 has incompatible type "Kern"; expected "Hlist | Vlist" [list-item] The check for the attribute _metrics is equivalent to checking for an instance of Char, since only Char and its subclasses set self._metrics. Mypy infers an unnecessarily tight type list[Hlist | Vlist] for spaced_nucleus so we give it a more general one.
