[gnome-shell/wip/fmuellner/overview-tweaks: 23/28] workspace: Only reveal title captions on hover

[Florian Müllner <fmuellner src gnome org>]

commit 152fc448b75af45289e4ee9406fd056727b0acd9
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.
