Redirect issue when using baseURL

[sidharthv96]

Describe the bug
This issue only happens when a site

• is deployed with paths.base config set
• a non root page is opened directly

https://example.com/base-path/test will load, but the URL will be rewritten to https://example.com/test.
So, when we refresh the page or copy paste the URL, the wrong path will be used resulting in 404.

I have identified the issue in

kit/packages/kit/src/runtime/client/router.js

Line 245 in a66affe

history.replaceState({}, '', `${info.path}${location.search}`);

and will raise a PR.

Logs
None

To Reproduce

• Set paths.base in config
• Deploy with static adapter
• Open url
• Refresh

Expected behavior
URL stays https://example.com/base-path/test
