[Enhancement] Kirby Avatar should handle broken links

jvh2 commented 3 months ago

[x] I have written a good issue

Describe the enhancement

Kirby avatar component should handle broken link for attribute [imageSrc] with an error handle event

Describe the solution you'd like

Kirby avatar component is expanded with a onerror event handler to handle broken links in [imageSrc]. Therefor we would like the kirby avatar component to be expanded with an error event handler.

Have you considered any alternatives?

Are there any additional context?

Tech Refinement As suggested the kirby-avatar should be extended with an onerror handler for the img within the avatar.

The native error handling is described here

As written in the error handling section of img elements in the mdn-site, there are multiple causes that may trigger the onerror. In that regard we intend to emit the full ErrorEvent since the consumer of this may need different information based on the cause of the error.

The event will be distributed through an EventEmitter<ErrorEvent> attribute: imgError which may be set on the kirby-avatar component to receive a callback when the img src returns an invalid image.
