Describe the bug
page.query not properly encoding/decoding params

Logs
https://www.amazon.com/Electronic-Arts-Titanfall-Instant-Access/dp/B01H0LFN3K/ref=as_li_ss_tl?ascsub=

To Reproduce

Pass in an encoded url with parameters to /?link=<encoded-url-here>

Use this url: https://www.amazon.com/Electronic-Arts-Titanfall-Instant-Access/dp/B01H0LFN3K/ref=as_li_ss_tl?&ascsub&linkCode=sl1&tag=foo-20&linkId=394efa83730b482f01461894f50da53f&language=en_US

it should be /?link=encodeURIComponent(url) when you send it

Expected behavior

<script context="module">
  export async function preload(page, session) {
    let scoops
    const { title, link, text, category } = page.query;

    console.log(link);
    if (text) scoops = 'text';
    
    return { title, link, text, category, scoops };
  }
</script>

console.log(link) here does not have any parameters after it.

Information about your Sapper Installation:

Ubuntu 18.04

"sapper": "^0.27.0",

Severity

I'd say not properly handling encoded url parameters is a major bug
