Calling the next attribute of an Annot raises a "No attribute .parent" warning

[jn-chrn]

Description of the bug

When reading annotations from a PDF page, we sometimes need the next attribute of Annot. However, when using this attribute, the following message appears in the terminal:

No attribute .parent: type(self)=<class 'fitz.Annot'> id(self)=139712888949840: have set id(self.parent)=139712932742416.

This occurs in version 1.23.21, but not in version 1.22.5.

The object itself seems to be accessible.

How to reproduce the bug

Using the following code returns the warning above when running it:

import fitz

doc = fitz.open()
page = doc.new_page()

page.add_line_annot((0, 0), (1, 1))
page.add_line_annot((1, 0), (0, 1))

first_annot, _ = page.annots()
first_annot.next.type
