[ui5-toolbar-ITEMS]: events are not dispatched correctly with a prefix

[MapTo0]

Bug Description

Hello Colleagues,

The events of all toolbar items are not dispatched correctly. Native events like Click work fine due to same mapping in the native word but custom events are not working the right way.

I see that there is already a test in the ToolbarSelect for that which is commented?
Please uncomment and fix the issue: https://github.com/SAP/ui5-webcomponents/blob/main/packages/main/test/specs/ToolbarSelect.spec.js#L35-L51

Since this is a blocker for our delivery I would consider that as a high / very high incident.
If you need more information regarding our use case feel free to contact me or Hristo Petrov.
