Legacy tag

This page embeds the leaflet with the deprecated <ip-embed experience="..."> tag instead of <ip-embed-leaflet alias="...">. Both tags are backed by the same element, the legacy one only differs in the attribute name used for the alias. Enter an alias (consisting of account slug and leaflet GUID) and click submit to set/change leaflet shown.

Things to verify in the browser console:

• A deprecation warning is logged when the element connects.
• The experience attribute is mirrored to the alias property on the element.
• on-ready / on-error callbacks and the error slot still work.
• getApi() resolves with a page-leaflet API.
