Hello,
If the is used in the context of an App Window, the secondary-actions won’t work if it uses the :
<s-page heading="foo">
<s-button-group slot="secondary-actions">
<s-button slot="secondary-actions" variant="secondary">Foo</s-button>
<s-button slot="secondary-actions" variant="secondary">Bar</s-button>
</s-button-group>
</s-page>
When used outside the context of an , this works as documented.
