Permissions Dialog can give wrong result for variants below a hippo:handle

For example when an admin in the /console navigates to

+ mydoc
    + mydoc (draft)
    + mydoc (preview)
    + mydoc (live)

and then selects the 'liveuser' to check read-access, the Permissions Dialog might indicate that the liveuser does not have read access to the live mydoc but to the draft

The reason is because the privileges are checked against an absolute path, for example against /content/documents/docs/mydoc/mydoc[3] but because the liveuser is not allowed to read mydoc[1] and mydoc[2] there is 'index' reshuffling happening, making the liveuser not being able to read mydoc[3] but only mydoc[1].
