CFormTextarea is not combining class attribute values

[leodotcloud]

If I try to set the class attribute for CFormTextarea as below, they are not passed on to in the final HTML.

Source:

<CFormTextarea class="border border-primary" placeholder="Start typing your note here ..." />

Rendered:

<textarea class="form-control" placeholder="Start typing your note here ..."></textarea>

The same seems to be working for some of the other components, example CCard.

I fixed it in v5.0.0-rc.2
