React SDK does not handle components children correctly when there are VDOM child nodes

Reproduction Path:
1. Go to `react-csr/src/App.tsx`.
2. Use the following code snippet instead `<BrComponent path="main" />`:

        <BrComponent path="main">
          <BrComponent path="container">
            <BrComponent></BrComponent>
          </BrComponent>
        </BrComponent>

Expected:
Container items are rendered without unnecessary markup.

Actual:
Container items are enclosed into `<div class="hst-container-item">` .
