Hi,

When using the dropdown tree on safari using the bootstrap themes when the page has scrollbars and clicking on the dropdown the page scrolls up, even though there is available space:

Please see this Dojo which replicates the issue:

Open the above URL in Safari, chick on the dropddown and the page scrolls up and the dropdown is no longer visible.

The problem is easily reproduced using the widget demo page https://demos.telerik.com/kendo-ui/dropdowntree/index

Simply switch to the High Contrast theme; the k-widget element is lacking the border-radius style hence looks different to the other widgets.

It looks like the k-dropdowntree class is missing from the following style rule:

.k-autocomplete, .k-block, .k-calendar-container, .k-colorpicker, .k-combobox, .k-datepicker, .k-datetimepicker, .k-drag-clue, .k-dropdown, .k-dropdown-wrap, .k-editor-inline, .k-grid .k-filter-options, .k-grouping-header .k-group-indicator, .k-inline-block, .k-list-container, .k-multiselect, .k-notification, .k-numeric-wrap, .k-numerictextbox, .k-picker-wrap, .k-slider-selection, .k-slider-track, .k-split-button, .k-textbox, .k-tile, .k-timepicker, .k-tooltip, .k-touch-scrollbar, .k-treeview .k-in, .k-upload, .k-window, .k-window-action, .k-window-titleless .k-window-content {
    border-radius: 13px
}

Hello Team,

Please refer this DoJo - http://dojo.telerik.com/@SaravanaMS/utINiRUq

We have a dropdowntree component added in a grid and when we collapse the dropdowntree options - dropdowm box stays at top.

Steps to reproduce - 

1. open all options from top to bottom 

2. collapse the option from bottom to top

3. once the top option is collapsed - dropdown box stays at top
