Platform(s)

iOS - iPad

Current Behavior

1. Open the keyboard, for instance by focusing a form input. (01_iPad_no_keyboard.png)
2. Observe how the <main> shadow node of the <ion-content> tag gets a padding-bottom value of 290px. (02_iPad_keyboard_did_show.png)
3. Close the keyboard by clicking the dismiss button on the keyboard.
4. Observe how the <main> shadow node of the <ion-content> tag still has the padding-bottom value of 290px that was added in step 1. (03_iPad_keyboard_did_hide.png)

Do not dismiss the keyboard by tapping the body. When the body is tapped, the padding-bottom is correctly removed.

Expected Behavior

When the keyboard is dismissed using the dismiss button, the padding-bottom value is removed from the <main> shadow node of the <ion-content> tag.

I can't reproduce on Capacitor 5 with @capacitor/keyboard 5 installed, so it was probably fixed.

If somebody still faces this or a similar issue, please, create a new issue on https://github.com/ionic-team/capacitor-plugins/issues and provide a sample app that reproduces it
