Two options are selected in the dhtmlxCombo

Hi team

I found the following problems.

If there three options(AAA,BBB,CCC) in the dhtmlxCombo and the order of the options like this .

AAA

BBB

CCC

For example ,the AAA has been selelcted.

Now , click the dhtmlxCombo and the option list will be displayed with the option AAA is selected.

Then move the cursor to the option CCC and the option CCC will be selected.

At this time , keep the position of the cursor on the option CCC and press the pagedown key , you will find both of the option AAA and option CCC are selected.



Thanks.

Problem confirmed and fixed - please use attached js file instead of original one.
