Google Optimize snippet causes pages to appear blank for several seconds on page load

[echeese]

Describe the issue

The Google Optimize page-hiding snippet isn't activated because of uBlock and thus must wait for a timeout.

This can be mitigated by calling window.dataLayer.hide.end() (if it exists)
