Custom Javascript is not Allowed / Taboola code

It makes no sense. After updating the Newspaper Theme to its latest, we’re getting “Custom Javascript is not allowed.”

I pinpointed it to the TABOOLA GOOGLE AMP code (advertising) as the culprit. Now, there has never been a problem with this code. It’s possible this falls squarely on the shoulders of Taboola, somehow, but it’s also possible something through WP for AMP or the Newspaper Theme (through WP for AMP) is creating this issue specifically through Taboola’s AMP code. Obviously, it could be something else, as well.

An ‘amp-embed’ line is what’s highlighted, more specifically, on the validator.

I reached out to Taboola as well, but wanted to drop this here just in case somebody else saw the same thing or knows where I should be looking to solve this thing. Thanks.
