Unable to drag to empty second column on dashboard

[ActionNerd]

If, for whatever reason, the second column on the dashboard is empty it appears to be impossible to drag new panels over.

Tried it with the default theme installed by first dragging all the panels to the first column. Once they're all in the first column, can no longer add to second column.

Can't reproduce. What browser, OS?

Chrome v19.0.1084.56
Firefox v13.0.1
OS X v10.7.4

I've made a small little movie file so you can see just in case: ​http://theexperiment.ca/files/dashboard.mov

What plugins are active, if any? I can see a plugin update notice in the movie, but it might be deactivated, right?

No active plugins.

Also a fresh install.

I reproduced on trunk with @ActionNerd's steps.

1. On dashboard, move all widgets to left column.
2. Try to move a widget to right column. Notice there will be no dashed option in the right column to move widget to.

So I'm not crazy? Well that's a first. Thanks!

This is an issue with responsiveness.

At a certain width of the screen, widgets remain in the second column, but once removed, they can no longer go back. If you make your window wider, eventually the dashed option will show up.

It happens at 1200 pixels. But two columns of full widgets don't wrap to one column until 800 pixels. These two values should probably be the same, at 800 pixels.

I feel like it can't possibly be this simple, but in my testing this worked: 21021.diff​

Patch looks good. As far as I remember this line was there to prevent the border when auto-switching to one column and the second column is empty, but that's handled few lines above.

Another related regression: IE8 doesn't like :empty and discards the other selector too. That results in not expanding the drop area, same as above.

Remove one more unneeded :empty
