# Function: syncInvoker()

> **syncInvoker**(`host`): `void`

Mirror the host's invoker attributes onto its inner `<button>`'s IDL properties, resolving ids
against the host's root so a shadow-DOM button can drive a light-DOM `[popover]`/command target.

## Parameters

### host

`HTMLElement`

## Returns

`void`
