Not able to get selection of PDF document

With PySide6 getSelection returns an invalid QPdfSelection. No matter what arguments we pass to it.

We'd expect a valid QPdfSelection with a non-zero boundingRectangle.

How to reproduce it

We call getAllText on a given QPdfDocument and we get a valid QPdfSelection and its boundingRectangle as expected:

selection: QPdfSelection = document.getAllText(1)
print(selection.isValid(), selection.boundingRectangle())
# True PySide6.QtCore.QRectF(72.000000, 72.000000, 451.000000, 728.000000)

But when we call getSelection we get an invalid QPdfSelection with a zero-ed boundingRectangle. No matter what arguments we pass to it (see below).

In our example here we use the top_left and bottom_right QPointFs of the boundingRectangle of the QPdfSelection returned by getAllText above:

top_left: QPointF = selection.boundingRectangle().topLeft()
bottom_right: QPointF = selection.boundingRectangle().bottomRight()
selection: QPdfSelection = document.getSelection(current_page, top_left, bottom_right)
print(selection.isValid(), selection.boundingRectangle())
# False PySide6.QtCore.QRectF(0.000000, 0.000000, 0.000000, 0.000000)

Minimal Reproducible Example

pip install pyside6==6.9.2

from PySide6.QtCore import QPointF
from PySide6.QtPdf import QPdfDocument, QPdfSelection

document: QPdfDocument = QPdfDocument(None)
document.load("filename.pdf")
current_page: int = 1

print("# getAllText()")
selection: QPdfSelection = document.getAllText(current_page)
print(selection.isValid(), selection.boundingRectangle())
# returns as expected:
# True PySide6.QtCore.QRectF(72.000000, 72.000000, 451.000000, 728.000000)

top_left: QPointF = selection.boundingRectangle().topLeft()
bottom_right: QPointF = selection.boundingRectangle().bottomRight()
print(top_left)
# PySide6.QtCore.QPointF(72.000000, 72.000000)
print(bottom_right)
# PySide6.QtCore.QPointF(523.000000, 800.000000)

print("# getSelection()")
selection: QPdfSelection = document.getSelection(current_page, top_left, bottom_right)
print(selection.isValid(), selection.boundingRectangle())
# doesn't returns as expected:
# False PySide6.QtCore.QRectF(0.000000, 0.000000, 0.000000, 0.000000)
