### Provide a general summary of the issue here

Currently, you can select multiple selections in a collection (e.g. Tree in this example).

However, the functionality lacks when doing the same action on a Checkbox within the collection items.

### 🤔 Expected Behavior?

Ideally, shift-clicking the Checkbox should behave the same and select items between.

### 😯 Current Behavior

Checkbox does not apply multi-selection functionality with keyboard actions.

### 💁 Possible Solution

Expose same events to slot="selection", that you already expose to the list
