I found the root cause: a structural nesting error in the raw HTML.
When the createCategoryModal element was generated, it was missing its outermost closing </div> tag. Because of this, the editCategoryModal wrapper became implicitly nested inside the createCategoryModal block in the browser's DOM tree.
Since createCategoryModal is naturally set to display: none (unless actively opened), simply telling the editCategoryModal to display did absolutely nothing because its parent structure was fully hidden!
I've manually appended the closing </div> structural tag to correctly isolate the two modal components.
Please refresh the support categories page and click the Edit operational command on any record again. It will now execute and open the edit dialog exactly as expected!
