uBlock prevents google fonts from loading sometimes

[cosban]

The issue begins if a font loaded from the google fonts api is used on an external site which links to a separate site using the same font. If the link which connects the two is clicked, the font begins to not load on both sites.

Below is proof of the bug:
This is the site before navigating to it from another domain.

ublock prevents the font from loading after navigating to it from the other site (clicking a link)

This is the error message within the console.

ublock is then turned off which allows the font to load:

The issue is able to be fixed by clearing the browser cache, but upon performing the navigation sequence again, the bug is reproduced.

Do you have "Experimental features" selected?

The issue does not persist if experimental features are turned off so if this issue does not fall under the correct umbrella, it may be closed.

Ok so it's a dup of #291.
