`ET.Element.tag` does not allow comparision with `ET.Comment`

To Reproduce

import xml.etree.ElementTree as ET

parser = ET.XMLParser(target=ET.TreeBuilder(insert_comments=True))
doc = ET.ElementTree().parse("foo.xml", parser)
for el in doc.findall("*"):
    if el.tag is ET.Comment:     #  error: Non-overlapping identity check (left operand type: "str", right operand type: "Callable[[str | None], Element[Callable[..., Element[Any]]]]")  [comparison-overlap]
        print("Comment:", x.text)

Expected Behavior

el.tag should be allowed to be compared to ET.Comment

Actual Behavior

el.tag is constrained to str only and raises following comparision-overlap error when compared with ET.Comment:
# error: Non-overlapping identity check (left operand type: "str", right operand type: "Callable[[str | None], Element[Callable[..., Element[Any]]]]") [comparison-overlap]

This error started after upgrading from mypy 1.14 to 1.15, most likely caused by https://github.com/python/typeshed/pull/13349

Tbh this isn't exactly documented behaviour and parsing comments programmatically isn't exactly best practice either, but some times you are not in control of the xmls received and reading the tag is the the only way to identify the comments that i know.

Your Environment

• Mypy version used: 1.17
• Mypy command-line flags: mypy --strict test.py
• Python version used: 3.13

Inizia individuando le definizioni dei tipi di xml.etree.ElementTree e riproduci il problema con lo snippet test.py fornito usando Python 3.13 e mypy 1.17 con --strict. Il lavoro è completato quando il confronto di identità tra el.tag e ET.Comment non produce più comparison-overlap, mentre il parsing dei commenti continua a essere rappresentato correttamente.
