"Undefined" shows in address input of lwc input-address when show-address-lookup is combined with show-compact-address

Description

Steps to Reproduce

1. Use this simple example copied from the lwc input-address documentation:

   <lightning-input-address
   show-address-lookup
   show-compact-address
   address-label="Address"
   street-label="Street"
   city-label="City"
   country-label="Country"
   province-label="State"
   postal-code-label="PostalCode"
   street="1 Market St."
   city="San Francisco"
   country="US"
   province="CA"
   postal-code="94105"
   field-level-help="Enter your billing address"
   >
   </lightning-input-address>

2. Make sure both show-address-lookup and show-compact-address attributes are used.
3. Observe that the rendered output shows "undefined" in the address input.
4. Remove show-compact-address attribute and "undefined" is not displayed in the address bar.

This is an issue with a Lightning Component, not the LWC framework (this repo). To resolve your issue, I would recommend opening a Salesforce Stack Exchange question or a Salesforce case.
