Expected Behavior

Suppose I have a dialog element with an autofocus input:

<dialog>
  <label>
    This should be auto-focused and editable:
    <input autofocus />
  </label>
</dialog>

Now suppose I want to show that dialog:

document.querySelector('dialog').showModal();

The input element is auto-focused as expected and all is well.

Actual Behavior

However, now suppose I want to show that dialog after showing a standard alert() or confirm():

alert('This alert will block the focusable element.');
document.querySelector('dialog').showModal();

The input element is no longer focused, is no longer editable, and seemingly completely stuck until I give focus to a different window entirely, and then come back to the Electron app.

Additional Information

This type of thing works fine in Google Chrome. It seems to be an issue specific to Electron.
