bug#61169: 29.0.60; python-ts-mode interferes with the major-mode of other files.

[xiliuya via Bug reports for GNU Emacs, the Swiss army knife of text editors]

Hello Emacs maintainers,

I apologize in advance for any mistakes since English is not my native language and it is the first time that I report a bug.

How to reproduce:
1) mkdir python
2) touch python/a.el
3) touch python/a.py
4) emacs -Q
5) C-x C-f python/a.py
6) M-x python-ts-mode
7) C-x C-f python/a.el

And then the major-mode of the el file became python-ts-mode.
