On firefox, the status picker dropdown needs to be held down in order to be selected

The status picker in the "Versions" menu is rather hard to use.

You need to open the versions dropdown
then click on the status dropdown (on the arrow on the right)
keep the left button pushed
drag the mouse up or down to choose the status to set.

The expected behaviour is to be able to click on the arrow to open the select
then lift the mouse button
then choose a status by clicking again on the chosen status
