// The idea behind is pages using a shared nextId() which returns an incrementing id
// So all responses should strictly be different and length of unique responses should equal to responses
// We strictly compare <foorbar>{id}</foorbar> section
// Because other response parts such as window.__NUXT may be different resulting false positive passes.
