chosen map element mass update properties remain selected

in a map, add 4 elements. select two of them, mark checkbox next to 'label', enter some label, click apply.
now select the other two elements - checkbox next to 'label' is still selected and will remove label for these hosts even if another property is changed. mass update checkboxes should be unselected each time mass update form disappears (but not when multiple hosts are selected or unselected and mass update form stays open)
