HintAssist.FloatingOffset not working on floating hint text boxes in latest release

[malu222]

Steps to recreate:

Just create two textboxes, one with offset and one without: they actually look the same

 <TextBox    Style="{StaticResource MaterialDesignFloatingHintTextBox}"
                     materialDesign:HintAssist.Hint="Hint without offset"
                     Text="Something}">

<TextBox    Style="{StaticResource MaterialDesignFloatingHintTextBox}"
                     materialDesign:HintAssist.Hint="Hint with offset"
                     materialDesign:HintAssist.FloatingOffset="1,-42"
                     Text="Something}">
