Another issue: It appears that two-level subcategories in the Categories list are not well supported, with the text and icon positioned too far to the left, to the extent that there is a significant risk that the rounded corners of the Category block under this theme cannot ensure the icon is contained within its boundaries.
In the screenshot, there are indeed three-level subcategories enabled through hidden settings, but they only change the style on top of the same layout as the Foundation theme, which is unrelated to the display issue of two-level subcategories that is the main focus of this question, and they have no visual errors.
