Bug: line highlighting doesn't work without line numbers #151
Description
When line numbers are not enabled, line highlighting doesn't work. It still fades out everything else, but it does not highlight the desired lines.
This fails:
const code = `<html>
<body>
</body>
</html>`;
<CodeBlock
text={code}
language="html"
showLineNumbers={false}
highlight="2-3"
/>But this works:
const code = `<html>
<body>
</body>
</html>`;
<CodeBlock
text={code}
language="html"
showLineNumbers={true} // The only difference
highlight="2-3"
/>
