Subject: Fix menu not shrinking to content properly

Before this commit, the width of the context menu depended on its own
previous width - so if you opened the menu of an album with a very long
name, then opened the menu of a shorter one, the width wouldn't actually
shrink to the shorter one's size as it's supposed to.
