Grid grouping + aggregates performance in WebAssembly apps is considerably slower (test project is available in ticket 1562161). Please research for ways to improve it.

In our serverside blazor application we use the Telerik's DateTimePicker. When we type values in to the date time picker control, it jumps to the next section or to the end before completing the currect section. We use the format 'yyyy-MM-dd HH:mm'

It does not happen always and I think it is happenning when the internet connection is slow and it shows a Javascript error as well (screenshots below)

This issue is for all date inputs when having a higher latency (physical distance between the server and the end-user) the value of the date inputs is not correct. Additionally, When typing the year in the input field, the text overflows instead of staying within the 4-digit space. For reference, check the attached screenshot.

Currently, on mobile devices (where is no hover), to open the child menu you need to click/tap the parent and the only way close it afterwards is if you click away. This is not very convenient for mobile usage. I want to be able to close the child menu on click/tap of the parent as well.
