[plugin] WP Use parent template not working

The WP Use parent template didn’t work as expected.

When the child category query is redirected to parent category template, the child category query is replaced by a global query. Oops, wrong behavior.

I’m still trying to find a plugin that does something obvious: uses the parent category template for child category queries. This would save me some elaborate conditional coding on the category page, or save me the horrid redundancy of multiple nearly-identical category templates for each category.
