With Firefox 60.0.2, I cannot focus password inputs inside modals.

Observed behavior: When I click on the password entry, no cursor appears. Expected behavior: When I click on the password entry, a cursor appears and I can start typing.

See the following code or click here for a fiddle:

<div id="app">
  <b-btn v-b-modal.modal-center>open modal</b-btn>

  <b-modal id="modal-center" title="password test">
    <b-form-input type="text"></b-form-input>     <!-- has a cursor -->
    <b-form-input type="password"></b-form-input> <!-- cannot gain focus -->
  </b-modal>
</div>
