Hi.

I can reproduce this issue too.

Please open following link:

http://jsfiddle.net/pye8nkps/1/

Move first square over second one.

Drop it.

After it move the square from second to third and return it back to second without dropping.

Do it quickly

You will see following:

over

over

out

over2

over

out2

'out2' should be before 'over'
