**Describe your issue**

In case we use some text wrapped with square brackets we get abnormal css output:

**Example 1:**
Just an object with string field:

This is probably because of [arbitrary properties](https://tailwindcss.com/docs/adding-custom-styles#arbitrary-properties). 

you can just add an unnecessary escape:
```ts
const ProblemComponent = () => {
  return (
    <button
      nCanPlay={(event: any) => {
        console.debug(`player ready: [autoplay\:${autoplay}]`);
      }}
    ></button>
  );
};
```

you can also use a function like this:
```ts
const addBrackets = (str: string) => `[${str}]`;

const ProblemComponent = () => {
  return (
    <button
      nCanPlay={(event: any) => {
        console.debug(`player ready: ${addBrackets(`autoplay:${autoplay}`)}]`);
      }}
    ></button>
  );
};
```
