sendPageView should be called via requestAnimationFrame, when available

[d4h0]

Hi,

The following code of this plugin is based on code from gatsby-plugin-google-analytics:

    // Minimum delay for reactHelmet's requestAnimationFrame
    const delay = Math.max(32, 0)
    setTimeout(sendPageView, delay)

In browsers with a refresh rate higher than 60, this can lead to a bug (where the wrong title is sent).

You can find more information in the issue I have created for gatsby-plugin-google-analytics:

gatsby-plugin-google-analytics: sendPageView should be called via requestAnimationFrame, when available #28591

I have the same issue, I also tried the solution mentioned here in local and tested using iphones in browserstack but didn't solve the issue, still pushing the previous page title.

This issue happens only in ios devices, mainly iphones. Haven't seen the issue happen in any other devices.
