Ionic Framework Version

• v4.x

Current Behavior

Using a custom class in global.scss, cannot scale a modal's height based on its content. No modal content appears except the modal backdrop.

ion-modal {
    --background: #fff;

    &.auto-height {
        --border-radius: 16px;

        &::part(content) {
            width: 95vw;
            max-width: 450px;
            height: auto;
        }
    }
}

Expected Behavior

Expect to be able to scale modal height automatically based on its content.

Steps to Reproduce

Display a modal using the ModalController and set its class to use the .auto-height class in the css above.
