[gnome-shell/wip/fmuellner/overview-tweaks: 5/9] workspace: Only reveal title captions on hover

[Florian Müllner <fmuellner src gnome org>]

commit ff2b5540a868a782a90f2d2cfff35b58f71b4c95
Author: Florian Müllner <fmuellner gnome org>

    workspace: Only reveal title captions on hover
    
    While the new title position gives the previews more space, they now
    overlay the content which may hide valuable information. Address this
    by only revealing the title as additional information on hover, like
    we do for other auxiliary elements.
