SplitButton can not raise Command

[CodingOctocat]

Describe the bug

I create a SplitButton, At first I used Click event, but clicking on the dropdown button also triggers Click event, which is not what I want.

Then I used Command, but it never triggered the command. I tried HandyControl's SimpleRelayCommand, AsyncComand etc. but to no avail!

1. Create a SplitButton

I created a new simple example, but I can't reproduce the problem either, and since my problem project has changed, I can't restore it for now, and this issue is closed for now.
