Describe the bug
When RadzenSplitButton component is used with a lot of subitems, strange scroll behavior can be observed. Instead of the scroll showing inside a control, it is rendered next to page scroll (see below screens) and using it causes scrolling through empty page as there are two separate scrolls now and page one is not scrolling. Is it desired behavior? Shouldn't it behave similar to RadzenDropDown scroll?

To Reproduce
Steps to reproduce the behavior:
Create RadzenSplitButton with lot of options that do not fit into page vertically. Documentation page can be used: https://blazor.radzen.com/splitbutton. Add a lot of options for any of the split buttons and click on it. Scroll down with cursor inised split button options.

Expected behavior
Would't it be a better user experience if the scroll would be rendered similar to RadzenDropDown?
