DHTMLX Combo dropdown not opening up on mouse click in Internet Explorer 11 Enterprise mode


I am using Internet Explorer 11 Enterprise mode - Document mode 8.
When we try to open the combo drop-down options by clicking on it using mouse it does not open up only to allow me to select an option. But it works perfectly fine using keyboard arrow keys.

Any help would be highly appreciated.
