[Bug] Kepler GL has a good amount of whitespace on bottom

**Description**
In my 2K LG monitor, there is a very big white space on the bottom.

**To Reproduce**
Steps to reproduce the behavior:

Here is the code I used:

```jsx

import { KeplerGl } from "@kepler.gl/components";
import { AutoSizer } from "react-virtualized";

function App() {
return (

export default App;

```

**Screen Recording**

Start by reproducing the issue with the provided React example using KeplerGl and AutoSizer on a 2K display, comparing the result with the attached screen recording. Trace how the supplied height is used by the KeplerGl component and determine when the bottom whitespace appears. Done means the example fills the available viewport without the reported whitespace.
