Dropdown drop up issue

I have two radzen dropdowns in a footer on a blazor page. Because the dropdown is at the very bottom of the page, I expect the content to be displayed above the component. The dropdown displays the content incorrectly the first time you click it, but then displays correctly when you click it again.
Radzen-Dropdown-Issue

I'm unable to reproduce such problem on our demos:
dd-dropup

Make sure you are using the latest version of Radzen.Blazor.

The Radzen.Blazor nuget package is up to date. I did some more debugging, and the problem stops occurring when I set the property AllowVirtualization to false. This is not a valid solution for me though, as I need the virtualization enabled for performance.

The demo I’ve tested doesn’t have any virtualization.
