resizableTextArea missing from Studio Palette, and doesn't render if added manually

So according to ResizableTextArea - CUBA Platform. Developer’s Manual there’s a resizableTextArea component. It’s not on the Designer’s palette, and if I manually change a textArea to a resizableTextArea in the XML, it works, but it doesn’t render correctly in the designer.

I’m wanting to use this so I can restrict how much a user can resize said area, so that they don’t resize it off the tab sheet. (Sigh, yes, I know.)

I’m guessing this is a studio bug/oversight? (@AlexBudarov edited the post and tagged it studio.)

We’ve created an issue to support resizableTextArea in Studio.
