Ionic Framework Version

v8.x

Current Behavior

On iOS only, if you use IonModal and have an input box with the keyboard up, when you dismiss the modal, it animates sliding off the screen. Unfortunately, it seems to slide to a position assuming the keyboard remains visible. When the keyboard is hidden, you can still see the modal sitting at the bottom for a second before it disappears. I found an existing issue that describes it better than me and has a video demonstrating it: #20686 I know that issue says it's fixed in Ionic 5, but if that's true, it seems to be back. I plan to work around the issue with

        Keyboard.hide().then(() => {
            setTimeout(() => {
                 this.modalCtrl.dismiss();
            }, 150);
        });

Basically using the Capacitor Keyboard plugin to hide the keyboard, give it a little time for animations and then dismissing the modal (inspired by the suggestion on the old issue.

Expected Behavior

Dismissing IonModal should have it slide down smoothly off the screen.

Steps to Reproduce

Open an IonModal that has an input box
Focus the input box so that the keyboard appears (if using the Simulator, you may need to turn off hardware keyboard)
Dismiss the IonModal
