Dialog examples only work as expected on the demo page

[IvankoB]

This example code placed in 'App.svelte' of bare TS-project displays both dialog contents (though shouldn't because 'open' var is false by default) and dialog call button

<Dialog
  bind:open
  aria-labelledby="simple-title"
  aria-describedby="simple-content"
>
  <!-- Title cannot contain leading whitespace due to mdc-typography-baseline-top() -->
  <Title id="simple-title">Dialog Title</Title>
  <Content id="simple-content">Super awesome dialog body text?</Content>
  <Actions>
    <Button on:click={() => (clicked = 'No')}>
      <Label>No</Label>
    </Button>
    <Button on:click={() => (clicked = 'Yes')}>
      <Label>Yes</Label>
    </Button>
  </Actions>
</Dialog>

<Button on:click={() => (open = true)}>
  <Label>Open Dialog</Label>
</Button>

<pre class="status">Clicked: {clicked}</pre>

<script lang="ts">
  import Dialog, { Title, Content, Actions } from '@smui/dialog';
  import Button, { Label } from '@smui/button';

  let open = false;
  let clicked = 'Nothing yet.';
</script>

Did you make sure to put <link rel="stylesheet" href="/smui.css" /> in your app.html and run npm run prepare after installing the packages?

As me understang that dialogs expect a theme to be specified to work properly.
Quite countrintuitive though ))

Not really. These components still rely on styling to display properly. If you don't reference the styles needed to make it function properly, it's not going to function properly.
