Using this renderer, component doesn't actually render anything

Hello Conor,

I am trying to incorporate your virtualized-renderer into our component since our code snippets are often very heavy (around 5k lines of code on average) and render-expensive.

No matter what I tried, changed or modified, eventually removing every customization and trying to use it directly as it is in the example,

Once the `renderer={virtualizedRenderer()}` prop is added, nothing is rendered:

Once it's removed, customized completely or not at all, the code passed to the highlighter is rendered normally:

Kind of at a loss here since I tried literally everything I could think of.

Any help would be appreciated.
Thanks

Start by reproducing the example with the `renderer={virtualizedRenderer()}` prop, then compare it with the same code rendered without that prop. Investigate why the renderer produces no visible output; done means the component displays the provided code while using the virtualized renderer.
