Path's joined wrong if encoding is disabled

[daniil4udo]

I am trying to join path for the router (which is using path-to-regexp).

const path = properUrlJoin('some-path', '/:id?/:subnav?/:step?', {
    trailingSlash: true,
    queryOptions: {
        encode: false,
    },
})

expected output should be

/some-path/:id?/:subnav?/:step?/

but it results to

/flow/:id/?/:subnav?/:step?

I guess that’s because ? has a special meaning in the url. It’s being interpreted as a query string.
