Problem

On /regression/, when selecting a category that has no associated tags, the category description is not displayed. The description field is present in the template but remains hidden.

Steps to Reproduce

1. Navigate to /regression/
2. Select a category that has no tags associated with it
3. Observe that the category description is not shown

Expected Behavior

The category description should be displayed when a category is selected, regardless of whether tags are available or not.

Actual Behavior

The category description remains hidden when no tags are available for the selected category.

Root Cause

The JavaScript function searchRegressionTests() is responsible for showing/hiding category descriptions, but it's only called when tags change or category changes, not on initial page load when no tags are selected.

Environment

• Browser: All browsers
• Platform: CCExtractor Sample Platform
• Page: /regression/
