Clearing selected autocomplete item is causing UI issue
I have 3 SFAutoComplete components, changing the value of the first one is resetting the selected values of the other two, each component is bound by SelectedItem property with a property in the view model.
When Items1_ChangedCommand selection changed event is triggered, I'm setting SelectedItem2 and SelectedItem3 to null, I also tried to call autoComplete.Clear() and autoComplete.IsFocused = false for them with no use.
Setting the SelectedItem2 and
SelectedItem3 to null is forcing the Focus and the suggestion box to be shown for both of them, which causes the suggestion box sometimes to be shown empty with this design. 
<autocomplete:SfAutoComplete
DataSource="{Binding Items1}"
SelectedItem="{Binding SelectedItem1, Mode=TwoWay}"
DisplayMemberPath="Name"
ShowSuggestionsOnFocus="True" >
<autocomplete:SfAutoComplete.Behaviors>
<behaviors:EventToCommandBehavior EventName="SelectionChanged"
Command="{Binding Items1_ChangedCommand}" />
</autocomplete:SfAutoComplete.Behaviors>
</autocomplete:SfAutoComplete>
<autocomplete:SfAutoComplete
DataSource="{Binding Items2}"
SelectedItem="{Binding SelectedItem2, Mode=TwoWay}"
DisplayMemberPath=" Name"
ShowSuggestionsOnFocus="True" />
<autocomplete:SfAutoComplete
DataSource="{Binding Items3}"
SelectedItem="{Binding SelectedItem3, Mode=TwoWay}"
DisplayMemberPath=" Name"
ShowSuggestionsOnFocus="True" />
