to_url doesn't support accessing parameter which contains dot

[tanapoln]

Problem description

Steps to reproduce the problem

1. assumed that url is looks like this https://example.com/?query.with=dot
2. parse url with to_url and assumed that the result is assigned to variable name url
3. cannot access query.with using url.queryParams.query.with or whether url.queryParams["query.with"]

I'm not sure is there any way to access the field, or do we have to escape the dot.
