RunWithContext takes a long time to run after context is cancelled

[TarakanoLov]

Hello, I expected that when calling RunWithContext the execution time would be limited to five seconds, but in fact the code runs for more than two minutes.
Is this expected behavior? Is there anything I can do to accurately limit the execution time?

Version: github.com/itchyny/gojq v0.12.19
Code:

package main

import (
    "github.com/itchyny/gojq"
    "context"
    "time"
)

func main() {
    parsed, err := gojq.Parse("capture(\"^\"*78888880)")
    if err != nil {
        panic(err)
    }

    code, err := gojq.Compile(parsed)
    if err != nil {
        panic(err)
    }

    ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second)
    defer cancel()

    iter := code.RunWithContext(ctx, "hello")
    _, _ = iter.Next()
}

Can you suggest a way to limit the execution time of regexp.Compile?

There is some talks about it here golang/go#67278. The only way i can come up with is using a custom io.RuneReader somehow but not sure that will work in all cases and how much performance impact it would have.
