What steps will reproduce the problem?
1. Add a credit card with no billing address through settings. For example, 4111 1111 1111 1111.
2. Open https://rsolomakhin.github.io/pr/type/debit/
3. Click "Buy" on page.
4. Click "Choose" in the "Payment" section of the PR UI.
5. Click "Add" button next to the billing address dropdown.
6. Add a valid address and click "Done" in the address editor.
7. Click "Done" in the card editor.

What is the expected result?
Card editor should close.

What happens instead of that?
The billing address dropdown is highlighted with a red border, which indicates that the address has not been selected yet. However, the address is selected (see screenshot). It appears that the data model has not been updated to reflect the UI state.

Please provide any additional information below. Attach a screenshot if
possible.

After clicking on the dropdown and re-selecting the same billing address again, the red highlight goes away and the "Done" button works again in the card editor view.
