Normalization throws for relative path with colon ':'

13] pry(main)> u = Addressable::URI.parse('../folder:2/readme.md')
=> #<Addressable::URI:0x1de84 URI:../folder:2/readme.md>
[14] pry(main)> u.normalize
Addressable::URI::InvalidURIError: Cannot assemble URI string with ambiguous path: 'folder:2/readme.md'

I expect folder%2F2/readme.md and a successful return. Should that be the case? The issue would then point to the regex below which does not take the relative part into account which gets trimmed as per standard.
