QSpinBox::editingFinished should not fire when contents haven’t changed

QLineEdit::editingFinished is documented as

This signal is emitted when the Return or Enter key is used, or if the line edit loses focus and its contents have changed since the last time this signal was emitted.

(Emphasis mine)

QSpinBox::editingFinished (and promoted QAbstractSpinBox::editingFinished new in Qt 6.10) on the other hand is emitted regardless of the value changing.

So, it’s working “as designed” but imho they should behave the same. Typing into a SpinBox is identical from a user’s POV to typing into a TextField.
