Btw, if { "scope": "/" } on https://cnet.com/tech-today/manifest.json then it should become https://cnet.com

{ "scope": "./" on the other hand would become https://cnet.com/tech-today/ as relative urls are relative to the manifest location.

I believe it is currently defined relative to manifest location and not start_url

4. Let scope URL be a new URL using value as input and manifest URL as the base URL.

> new URL("index.html", "https://i.rocks/manifest/manifest.json").href
< "https://i.rocks/manifest/index.html"

> new URL("/", "https://i.rocks/manifest/manifest.json").href
< "https://i.rocks/"

> new URL("./", "https://i.rocks/manifest/manifest.json").href
< "https://i.rocks/manifest/"

This bug is about how we handle scope when the scope is undeclared. I think that Chrome correctly handles scope when scope is declared.

Thank you for the w3c spec links

Do not drop the final web app scope path component if it ends with a slash.

This CL updates the web app scope computation. The current computation
drops the final component of the path if there is more than one
component. For web apps which have a start URL that ends in a folder,
this removes the containing folder, resulting in an overly broad scope.
For instance, https://example.com/today/ would end up with a scope
over all of https://example.com under this scheme.

Instead, we refine the computation by not dropping the final path
component if the path ends with a slash. This indicates that the final
component is a directory which should be retained. Otherwise, a lack of
a slash at the end of the path signals a file, which we remove to
extract the containing directory.
