Subject: 28.0.50; python-mode font-lock assignment issues

[Message part 1 (text/plain, inline)]

emacs-version: "GNU Emacs 28.0.50 (build 1, x86_64-pc-linux-gnu, GTK+
Version 3.24.24, cairo version 1.17.4)
 of 2021-01-22"

Sometimes assignments are not fontified or fontified incorrectly.
Steps to reproduce:
1. Create a python file with contents
> def foo(bar: int) -> str:
>     spam = bar
>     eggs = f'lkjahsd {spam}'
>     return eggs
>
>
> def foo2(bar: int):
>     spam = bar
>     eggs = f'lkjahsd {spam}'
>     return eggs
>
>
> def foo3(bar):
>     spam = bar
>     eggs = f'lkjahsd {spam}'
>     return eggs

2. Open the file with emacs -Q

You will see that variables `spam` and `bar` are highlighted differently
in all 3 cases.
`spam`:
  not highlighted at all in cases `foo` and `foo2`
`bar`:
  not highlighted correctly in cases `foo` and `foo3`

Best regards,
Mykhailo

Is this the same bug as in Bug#45679?

It certainly can be, yes.
Fixing one will probably fix the other. But I decided not to guess and file
this report as well, as the described case is a bit different

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

I can reproduce this in Emacs 28, but not in Emacs 29, so it seems like
this has been fixed in the time since this was reported, and I'm
therefore closing this bug report.
