Fix usage of preferred width in task manager / scrollable panel Previously the panel would use Layout.preferredWidth, which is always -1; it now instead uses implicitWidth, which is the correct value. This commit also brings back the correct preferred height calculation for horizontal panels in the task manager.

Created attachment 184663 [details] window group vanishing into the void I could still reproduce it the last days. It happened when a was removed from the taskmanager either by closing or moving somewhere and this causing grouped tasks to become ungrouped. I just tried again and instead of this behavior window groups now just vanish.
