This has been part of tile since the component's inception 7 years ago d2d64a2

My understanding is the tabindex is set to zero to ensure the tile gets focus. When an anchor tag doesn't have an href, focus does not move to the anchor tag, it's skipped. This effectively means the tile is a placeholder link

@mbgower Would adding role='button' be a reasonable course of action here? Or is this pointing to needing to reconsider the markup of the tiles that have this?

@anish-mm-05 is there a reason why you're using ClickableTile instead of SelectableTile? If you provide href to ClickableTile as intended there are no violations. Based on your screenshot it seems like your usecase would call for SelectableTile over ClickableTile.

It is odd that ClickableTile's href isn't a required prop. Maybe that's the real solution here @mbgower?
