If a selector without non-standard CSS properties matches huge amount of elements, large amount of CPU and memory resources are required to check the non-standard CSS properties.
It means that checking process with non-standard CSS properties will take some times.
However, using p-limit npm package can execute a selector with non-standard CSS properties simultaneously according to navigator.hardwareConcurrency [^1].
It reduces the taking time to execute a selector to select the elements.
