Multiselect control cannot be recorded against IE as expected. When selecting more than one value from it, using the Ctrl key, not all selected options are listed in the 'SelectedItems' step property.
The 'SelectedItems' step property does not display names of the selected items and it is not visible how many elements there are to be selected.
If the desired items are manually added in the mentioned property, they will be selected correctly in run-time.
