Memoryblock: class "blockTopOpen" is not persistent

The class "blockTopOpen" is applied to the h2 header when you click to open a block.
But when you navigate to another page, it is forgetted.

I think there is a typo on memoryblock.js :

else if (status != 'closed' && status == 2) {
  top.attr("class","blockTopOpen") 
  createCookie(id, 'open', 1); 
}

The value for "status" cannot be "2", and this test is always false

This one is ok :

else if (status == 'open' || (status == null && setting == 2)) {
