0018978: Media tree icons are initially incorrect sometimes (after restart)
Description
While adding 'Title' node in course of 0018760 noticed this issue (happens only sometimes):
1) Enable 'Title' node under collection Music
2) Go to Music > Title > É
3) Restart MM5
=> it restores correctly to 'Music > Title > É'
but some of the tree icons are incorrectly assigned to collection icons
4) Scroll the Media Tree
=> icons are self-corrected
I've reproduced similar behaviour with playlist subnodes
