Bug in highlight for some cases of ranges of one-digit to double-digit

See [codebox](https://codesandbox.io/s/react-code-blocks-forked-7n4nq2?file=/src/index.js) for example

When setting a "1-10" or "1-11" in the highlight props, highlight is working as expected
However, when setting any other one-digit it fails to highlight the required rows, for example: "4-11" is not working as expected, and nothing is highlighted.
