Nodelist.ForEach is not a function.

[Kris-88]

The ForEach function is used, in particular, in the wpdiscuz wordpress plugin.
The problem can be solved by adding a line before scripts.
NodeList.prototype.forEach = Array.prototype.forEach;
Is there a way to insert this polyfill into omni.ja?
Or is it possible to incorporate it into the browser in some other way?

Ok, we can't change the engine, but maybe we can add a "content-document-global-created" event for macros and inject a polyfill script?
$OnLoad event fires too late.
