Overview: More detailed restatement of summary.

Scrolling through desktops on the workplace switcher goes in an out-of-order fashion with 2 rows.

Steps to Reproduce: Minimized, easy-to-follow steps that will trigger the bug. Include any special setup steps.

1) Set workplace switcher to 2 rows (right click on panel -> Panel -> Panel Preferences -> Items -> select Workplace Switcher -> "Edit currently selected item" -> set # of rows to 2).

2) Place cursor over the 1st workspace in the workspace switcher on the panel

3) Scroll down with the mouse scroll wheel

Actual Results: What the application did after performing the above steps.

Workspaces will scroll in the wrong order. It will be 1-3-2-4

Expected Results: What the application should have done, were the bug not present.

The workspace should scroll in correct order of workspaces, 1-2-3-4

It does not happen if I make the workspace switcher 1 row and scroll - this scrolls in correct order.
