Low Bounce rates on GA dashboard

[jonathanrosenbaum]

Describe the bug
Bounce rates in GA dashboard are showing as too low ie less than 1%.

To Reproduce
Steps to reproduce the behavior:
Add this snippet as per instructions. Config shouldn't matter as long as GA has been enabled.
Set cookie for google analytics as stated in read me ensure that cookie expiration date is set so that it won't be invalidated between refreshes.

Reload page. On all page reloads 2 page view events have been sent from the browser. One by default is sent from the google analytics script by default and the other from the 'trackGoogleAnalytics' fn inside of 'src/service/googleAnalytics.js'. View GA Dashboard

Expected behavior
A clear and concise description of what you expected to happen.

To overcome this we need to have the option to disable the initial page view event sent from the ga script. A property can be added to prevent this behaviour in the gtag('config', () =>{}) fn ie

window.gtag('config', options.trackingId, {
  'anonymize_ip': gaAnonymize,
  'allow_google_signals': gaAllowAdFeatures,
  'send_page_view': gaPageViewOnLoad
});

However currently this option hasn't been provided.
