PanGestureRecognizer with non-primary button gets cancelled when dragging out of the window #166309
Description
Steps to reproduce
- Run as Windows Application
- Press middle mouse button on the blue container
- Hold and drag it out of the application window
Expected results
The gesture recognizer still receives updates when dragging out of the window until the mouse button is released
Actual results
The gesture recognizer invokes onEnd immediately after dragging it out of the window
This does not happen with primary mouse button, when using primary mouse button, the gesture recognizer still receives pointer update even when the cursor is no longer inside the application window.

debugOwner: this,

//return buttons & kTertiaryButton != 0;
return true;
},
),
(PanGestureRecognizer instance) {
instance.onStart = (details) {

};
instance.onUpdate = (details) {
print('onUpdate: ${details.globalPosition}');
};
instance.onEnd = (details) {
print('onEnd: ${details.globalPosition}');
};
instance.onCancel = () {
print('onCancel');
};
},
),

Reproducible using the code sample and steps provided above. This worked as expected on macOS. It most likely might be due to how lifecycle events are handled on windows. Labeling for further investigation
flutter doctor -v
