Issue Description

There is a discrepancy between the English and Japanese nested pages. The Japanese version is missing the interactive scene iframe content that is present in the English version.

English Version

Interactive Scene</label><div class="sd-tab-content docutils">
<iframe src='../../_static/static_viewer.html?fileURL=../_images/plot_directive/tutorial/00_intro/index-1_00_00.vtksz' width='100%%' height='400px' frameborder='0'></iframe></div>
</div>

Japanese Version

インタラクティブなシーン</label><div class="sd-tab-content docutils">
</div>

Expected Behavior

The Japanese version should include the same iframe content as the English version, displaying the interactive scene viewer.

Actual Behavior

The Japanese version has an empty tab content div with no iframe element.
