For site pages, if you add a "/" and any text after the URL, it displays the original page

Question:
I have created a Wix site. I noticed that for any of my site’s pages (eg. /products), if I add a / and any additional text, Wix will show the original page. So, for my products example, /products/foo and /products/bar will render my /products page.

The code of these pages show these new URLs as the canonical URLs.

This isn’t ideal for SEO as potentially if these pages were crawled you could have infinite URLs showing the same content. I’d much prefer these 404. Is this a setting I have missed? Or is this intended behavior? Or is it a bug?

Product:
Wix Studio

What are you trying to achieve:
I’d prefer that subpages like this, except those that are explicitly designated to have these URLs would 404.

What have you already tried:
I haven’t been able to find this documented anywhere.
