Library cannot use bind on the website with mootools

[drdmitry]

There is a website, which has mootools library loaded on the page.
When using Prebid 2.0 (with fun-hooks) - getting an error when the bind function is used.
The problem is that mootools re-defining the Function.prototype.bind.
See screenshot for some details.
Example (sample page) to be created.
What would you suggest for a fix? There is no access to change the website content (remove mootools).

Do you have a test URL I could see the live error at?
