    Description

      The following code:

      from PySide2 import QtWidgets

app = QtWidgets.QApplication([])
button = QtWidgets.QPushButton()
s1 = button.clicked
s2 = button.clicked

print(s1 == s2)
print(s1 is s2)

      prints

      True
True

      before version 5.15.2.

      However the same code prints

      False
False

      since 5.15.2.

      The regression makes it impossible to implement certain useful code patterns.

      It would be great if this regression can be fixed.
