Cannot index content embedded in Tabs

[yulius-take2]

It appears the content inside tabs are not indexed. I'm unable to search for content in tab[1-3].mdx.

import Tabs from '@theme/Tabs';
import TabItem from '@theme/TabItem';
import Tab1 from './tab1.mdx';
import Tab2 from './tab2.mdx';
import Tab3 from './tab3.mdx';

<Tabs>
  <TabItem value="Tab1" label="Tab1" default>
    <Tab1 />
  </TabItem>
  <TabItem value="Tab1" label="Tab1">
    <Tab2 />
  </TabItem>
  <TabItem value="Tab1" label="Tab1">
    <Tab3 />
  </TabItem>
</Tabs>
