There seems to be problems when using the kendo textarea with a floating label. When I input text und blur the field, the floating label gets a wrong position.

Furthermore the label is vertically centered in the field, when there is no content. Maybe it would look better to align it at the top like in the material components. This could also let the user decide the initial textarea height without alignment conflicts.
