popup height to show all elements

[Dituar]

If there are more than 18 groups, then in the pop-up window to display the remaining groups you have to scroll with the mouse wheel.
Please make it so (or enable the checkbox in the settings) that the height of the pop-up window is such that all elements of this pop-up window are displayed, so that you do not have to scroll with the mouse wheel, and only if there are more elements than the height of the browser window, the scroll bar is displayed.
