Public bug reported:

When browsing through OpenStack Swift containers, sometimes Horizon will
incorrectly encode part of the URL/URI of an object, and thus navigate
to the wrong page. This has been reproducible for me by placing an
object in a container more than about 3 pseudo-folders deep. For
example, the structure might look like:

(Container) --> folder1 --> folder2 --> folder3

Upon clicking on folder3 in the Container browser window in Horizon, the
site will try to navigate to
"containers/container/containername/testfolder1%2Ftestfolder2/testfolder3"
rather than the expected
"containers/container/containername/testfolder1/testfolder2/testfolder3".

It appears that at some stage in the process, the path gets HTTP URL
Encoded (encodeURIComponent) too many times. Note that the unexpected
character "%2F" is the encoding of "/".

This is also evident by snooping on the GET request Horizon makes to the
OpenStack Swift backend (see attached screenshot); the delimiter is set
as "%2F", but the path requested has a "%252F" (this is just the double
encoding of "%2F" since the encoding of "%" is "%25").

I'm guessing that there might be some recursive logic somewhere that
results in the end-string being encoded multiple times.
