bug#58814: Python.el major mode syntax highlighting not working

[Stan Staykov]

Using emacs 28.2 on Arch Linux.
Syntax highlighting using the default python-mode (python.el) is inconsistent.
Multiple users in the #emacs channel who all tested this with the -Q option all report the same results.

Please see attached image for the first example.

Notice how the variable 'money' for example is randomly highlighted.

Full code here: Paste.rs

For the above code, when opened in emacs -Q if you go to the last instance of 'money' where it says 'money += bet * 2' and press RETURN after the end of that line, suddenly it gets highlighted, and then if you go to the previous instance of that and do the same, the highlighting of the one below disappears.

The same was confirmed by multiple users from the #emacs channel.

Please advise.

Best regards,
Stan
