Horizontal scrollbar shown beween width: 40em and max-width: 53em

Hi, I have noticed that an horizontal scrollbar appears when you resize the screen on the latest template (http://www.ebi.ac.uk/services). I guess it is due to the EMBL-EBI icon on top right (that changes from EMBL-EBI Hinxton to just EMBL -EBI, before switching side) :

It works better when you turn those ones off (but doesn't do the nice effect on text):
@media screen and (max-width: 53em)
.embl-selector .button {
width: 0px;
padding-right: 0;
overflow: hidden;
}
