Issue #1

Given:

Controlled TextaArea componenet with autoSize and rows properties.

const App = () => {
  const [state, setState] = useState();

  return (
    <TextArea
      value={state}
      onChange={(e) => setState(e.value)}
      autoSize={true}
      rows={2}
    />
  );
};

When:

Add couple text lines to extend TextArea size and remove these empty lines in any way.

Then:

Content from TextArea field is removed but TextArea height stays the same, doesn't come back to it's initial value. It's different comparing to example from your docs where example contains uncontrolled component.

Issue #2

Given:

Controlled TextaArea componenet with autoSize and rows properties.

const App = () => {
  const [state, setState] = useState();

  return (
    <TextArea
      value={state}
      onChange={(e) => setState(e.value)}
      autoSize={true}
      rows={4}
    />
  );
};

and styles like these

.k-textarea textarea {
  border: 1px solid blue;
}

When:

Start typing anything

Then:

Height of textarea component is decreasing

Example on stack blitz

we have X(cross) for combo box but it is not coming for datetime picker 

Walkthrough component.

The component will allow the developer the create a step by step guide over the page.

This will highlight a collection of elements in a set order on the page with a tooltip showing the newly introduced feature.
