Blazor PWA: Start URL is wrong for sites not deployed to the root URL

[SteveSandersonMS]

The manifest.json file contains this: "start_url": "/"

However, if your site is deployed into a non-root location (e.g., http://example.com/mysubdir/), then this incorrectly resolves to http://example.com/.

To fix this, we need to change it to "start_url": "./". As per the spec, relative URLs are resolved relative to the location of manifest.json, so this would be correct in all cases.
