22504,Custom Header should reuse existing media frame,duck_,koopersmith,"Unlike custom-background.js, custom-header.js doesn't attempt to reuse an existing media frame. See [22502] and [22505].

This causes strange behaviour when closing and re-opening the media modal, e.g.

 1. Click ""Choose Image""
 1. Close the modal
 1. Click ""Choose Image""
 1. Attempt to go to the ""Upload Files"" tab

Expected: go to upload files

Actual: file browser opens because a new uploader instance was created with no left/bottom positioning CSS and blocks the link text

(NB: this missing CSS when multiple uploaders are created sounds like a potential issue elsewhere too)",defect (bug),closed,normal,3.5,Media,,normal,fixed,has-patch,
