Criterion 1.4.11 - what constitutes a clickable boundary?

There is a kind of UI component that doesn't seem to be addressed on the "Understanding Success Criterion 1.4.11: Non-text Contrast" page (https://www..w3.org/WAI/WCAG21/Understanding/non-text-contrast) -  a clickable "product tile", where the image of a product is displayed on a light-colored "tile"..



Here's an example from the Microsoft website (https://www.microsoft.com/en-us/store/collections/surfacelist?icid=MSCOM_QL_Surface&headerid=department-surface):



The light grey rectangle should be considered a UI component because it is clickable.  However, the light grey rectangle lacks sufficient contrast with the white background.



So, since the light grey rectangle IS the clickable border of this UI component and it does not have sufficient contrast with the white background, would it fail WCAG 1.4.11?
