+Subject: [PATCH] Only return valid task item size if task manager has been
+ resized to fit panel
+
+Previously the task manager would briefly have null width and height, before
+being resized to fit the panel. However, the "preferredMaxWidth" for tasks
+would still be positive, as it adds margins to it, and tasks would then
+assume a positive width. When the proper values are set, this casuses
+an extra resize animation.
