Performance issue: getMatchedCSSRules takes ~800ms, causing slowdowns during split operations

Hi,

I am experiencing a performance issue related to the getMatchedCSSRules method. During split operations, this method takes approximately 800ms to execute, causing noticeable slowdowns. In the image attached you can see a problem.

Have you considered adding a cache to this method or passing with options the value required for avoid search in all css rules?

Looking forward to your feedback
