bug: expose role attribute on ion-alert + ion-toast

[eric-horodyski]

Prequisites

• I have read the Contributing Guidelines.
• I agree to follow the Code of Conduct.
• I have searched for existing issues that already report this problem, without success.

Ionic Framework Version

• v4.x
• v5.x
• v6.x

Current Behavior

While working with a community member, it was observed that there is no way to modify the role attribute for the IonToast and IonAlert components.

Expected Behavior

As a developer, I would like to have the ability to set the role attribute as my application would like to set this attribute to alert for both components.

IonAlert sets role="dialog" but in this application's accessibility context it needs to be set to "alert".

Steps to Reproduce

Using the AlertController and ToastController there is no ability to manually set the role attribute.

Available in the next release of Framework, ion-toast and ion-alert will accept an htmlAttributes prop, which allows developers to pass arbitrary attributes to the host element, including role. Thanks!
