I have an issue with the DropDownList and Data Annotations.
I have created a REPL instance that demonstrates the problem https://blazorrepl.telerik.com/GyamPdlf37LXpPAW36
Select the last item in the tree 7.Garden and change the value in the drop down list to Unsupported.
The drop down list shows a red border.
Select item 6.Garden from the tree. (Any item in the tree other than 1 will do)
I expect the drop down to not have the red border, yet is does.
The text box does not show the same behaviour.
Select 7.Garden
Edit the email address to start with unsupported
The text box has the red border
Select any other item in the tree, they will not have the red border.
TBH I'm not sure if this is a Telerik/DropDownList issue or I'm doing something wrong.
The REPL example replicates an issue in a larger piece of code that is more complex with regards to the validation which is why there are no data annotations on properties and the binding are not simple.

Thanks
