What happened?

A stale elementArray of $$() that no longer exists crashes with Index out of bounds! $$(h1) returned only 0 elements. when iterating it's properties like isDisplayed().

What is your expected behavior?

Even a stale instances of $$() should not crash when trying to iterator through the array to fetch any of it's properties. It's should simply return an empty results

How to reproduce the bug.

typescript
        it.only('should be able to query isDisplayed on element no longer existing', async () => {
            await browser.url('https://guinea-pig.webdriver.io/')
            const h1 = $$('h1')
            await expect(await h1.length).toBeGreaterThan(0)
            await expect(await h1.map(el => el.isDisplayed())).toEqual([true, true])

            await browser.url('about:blank')

            await expect(await h1.map(el => el.isDisplayed())).toEqual([false, false])
        })
