page.annots(): ValueError: orphaned object: parent is None #2479
Description
I'm not sure what the expected behaviour is, but I'm getting a ValueError from .annots():
>> import fitz
>> fitz.version
Out[3]: ('1.22.3', '1.22.0', '20230510000001')
>> doc = fitz.open("DELETE_ME_tam_file_with_runtime_annot_errors.pdf")
>> list(doc[0].annots())
Out[8]: ---------------------------------------------------------------------------

I can't think why p.annots() would be different than doc[0].annots()...
