Steps to reproduce

Edge appears to be over-decoding URLs pasted into the address bar. For example, try pasting https://www.bing.com/%252F into the address bar. This is not just a visual display issue: for example, window.location.href will see the over-decoded value, and copying out of the URL bar results in a different value from what was pasted in.

  • Edge 40.15063.674.0 - changes to https://www.bing.com/%2F
  • IE 11.674.15063.0 - correctly preserves https://www.bing.com/%252F
  • Chrome 62.0.3202.75 - also correctly preserves.

I checked “This issue affects standards compliance,” since, for example the Location interface (https://www.w3.org/TR/html5/browsers.html#location) implements URLUtils (https://www.w3.org/TR/html5/infrastructure.html#urlutils), which has properties as discussed here: https://www.w3.org/TR/html5/references.html#refsURL, which refers to the URL standard, which states, in section 3.3, that URLs may contain percent-encoded characters: https://tools.ietf.org/html/rfc3986#section-3.3 and section 2.4, which states “Once produced, a URI is always in its percent-encoded form.” https://tools.ietf.org/html/rfc3986#section-2.4
