[wp-testers] 2.8 latest | All Dashboard modules aligned left

[Kirk M]

I've just updated my local WordPress sandbox to the latest 
("Stay Updated") build and noticed that when the Dashboard is 
set to 2 or more columns, all modules are aligned left and 
cannot be moved elsewhere. The modules can actually be moved 
but do not drop into any other column, snapping back to their 
original place in the left column.

Note: The modules resize correctly depending on how many 
columns I chose from the Screen options. They just won't drop 
anywhere except the left hand column. I can also rearrange the 
modules to different positions in the left hand column as well.

Anyone else seeing this?
