Problem Description

"match" and "case" are highlighted even as part of variable names. This issue is a continuation or reopening of #21239. The only change is that the incorrect highlighting has additional conditions. The thing to reproduce that I have found, there could be more conditions, is that there must be a colon, ":", in the line with "match" or "case".

What steps reproduce the problem?

1. open Spyder in dark mode (I did not check light mode)
2. open new .py file
3. type a word with "match" in it and then follow it with a colon, ":".

re_match = "asdf"           # Not highlighted
if re_match == "asdf":      # Highlighted
    pass

What is the expected output? What do you see instead?

Expected output is no highlighting of "match". I see highlighting of "match".
