The elements in `Grammar/python.gram` stripped by `peg_lexer.py` still shows in generated PO files

My original question has answered by Stan. I leave it here as a record:

I'm not sure if it's done deliberately, but it seems odd to me and I can't find out why it happens so far.

The reference/grammar.rst includes Grammar/python.gram

https://github.com/python/cpython/blob/78a50ee10ef73296eba98899d496bff3915ddc41/Doc/reference/grammar.rst#L18-L19

and Grammar/python.gram has a section for invalid rules at the bottom.

However, the content after START OF INVALID RULES is missing on the page

I checked the previous version and found out the doc has this issue since 3.11 (after PEG parser is introduced).

Other info:
I translated this page into Traditional Chinese (zh-tw) recently and somehow it shows correctly on the translated page

So here's the revised issue description:

Some elements in Grammar/python.gram are stripped by peg_lexer.py, and hence they're hidden on the reference/grammar docs. However, the full content of Grammar/python.gram is still remained in the generated PO files (e.g. the one in zh-tw).

Doc/tools/extensions/lexers/peg_lexer.py から始め、Grammar/python.gram の扱いを Doc/reference/grammar.rst への組み込みと比較してください。生成された reference/grammar.po の例を調べ、除去された内容がどこに残るのかを確認してください。Done では、レンダリングされたドキュメントと生成された PO ファイルの両方で、期待される扱いを定義し、一貫して適用する必要があります。
