Any transitioned event from a child element, like a radio button or button with a CSS transition, bubbles up to the TelerikWindow, triggers StateHasChanged on the window, which causes a re-render and leads to OnParametersSet being called.

Reproduction example: https://blazorrepl.telerik.com/wzEhnvOL011iIhls25.
To reproduce the issue:

1. Open the Window
2. Hover the Submit button or...
3. Hover the arrow buttons of the NumericTextBox or..
4. Select a new RadioGroup value

The NumericTextBox value is the OnParameterSet counter.
