Cannot pinch-to-zoom after the qt 6.7.1 upgrade [regression]

After the qt 6.7.1 upgrade, I cannot use the pinch-to-zoom feature on qutebrowser (which is a qtwebengine-based browser) anymore.

I used the testbrowser to test. When the qt packages are 6.7.0 I'm able to pinch-to-zoom, but when they're 6.7.1 I cannot do so anymore. Also, the other qtwebengine-based browser like konqueror have this issue as well.

Then I went to try an AI-generated cpp example to get a minimal example without qtwebengine, see attachment.
At 6.7.0, the QWidget can detect the QEvent::NativeGesture event, but at 6.7.1 there is no such gesture event got detected. And since this cpp example did not include qtwebengine, I guess this issue is not related to qtwebengine but qtwayland or qtbase.
