IsEnabled binding broken when adding an EventTrigger

I have this TextBox that is disabled when a CheckBox is ticked, using a binding on IsEnabled. This works fine on its own.

<TextBox Text="{MyValue}" IsEnabled="{Binding CheckBoxTicked}" />

<CheckBox IsChecked="{Binding CheckBoxTicked, Converter={StaticResource BoolInverterConverter}}"  />

I want to add a LostFocus event to this TextBox that will check if the value is correct using a command in the ViewModel.

<i:Interaction.Triggers>
    <i:EventTrigger EventName="LostFocus">
        <prism:InvokeCommandAction Command="{Binding LostFocusCommand}" />
    </i:EventTrigger>
</i:Interaction.Triggers>

This works too, but the IsEnabled binding gets broken when the trigger is added and the TextBox no longer reacts to the ticking of the CheckBox.

Try to remove the converter or replace <prism:InvokeCommandAction ... /> with <i:InvokeCommandAction ... />. Then it should work.
