i am playing around with the new SPA-renderer in our demo. I just recognized that the component variants select box is not working properly in the current snapshot version of the personalization stuff 2.1.1-SNAPSHOT. Is this a known issue?To be more specific. * The variant creation is working as expected

• The variants are visible in the select box
• Changing the variant in the Dialog is no problem
• But changing the variant does not affect the preview in the editor
• So i always see the original variant
• The selected variant stays on “0riginal” (see Screenshot)

We use this three snapshot version to be able to use the the site aware spa-renderer in the sales-demo:

      <dependency>
        <groupId>info.magnolia.pages</groupId>
        <artifactId>magnolia-spa-rendering</artifactId>
        <version>6.2.17-SNAPSHOT</version>
      </dependency>

      <dependency>
        <groupId>info.magnolia.pages</groupId>
        <artifactId>magnolia-site-spa-rendering</artifactId>
        <version>6.2.17-SNAPSHOT</version>
      </dependency>

      <dependency>
        <groupId>info.magnolia.pages</groupId>
        <artifactId>magnolia-pages-app</artifactId>
        <version>6.2.17-SNAPSHOT</version>
      </dependency> 

We added this three modules to the sfcc Demo and after this we saw the same behaviour as in the sales-demo.
