`width` applies only on `<Input />`

[Adnan Asani]

Given the following code;

          <Omnibar
            extensions={[SearchExtension]}
            rootStyle={{
              border: '1px solid #f00',
              position: 'relative',
              marginTop: '50px',
            }}
            width={300}
          />

we get this

This now brings me back to my original concern of width and height
