Please enable some way we could use the masonry layout javascript package.
All I need is some way to get this URL in the header and I would be good to go:
<script src="https://unpkg.com/masonry-layout@4/dist/masonry.pkgd.min.js"></script>
But with javascript blocked I can't. And with javascript forced through an iFrame, I can't send any data into that iFrame for rendering.
Bootstrap 4.0 has masonry built into it. So upgrading, or allowing a theme layout to upgrade to it would also solve this problem.
Although in general, it would be great if you could supply a list of approved javascript packages that can be enabled on a theme layout, and a means for us to submit a request for a package to be added to that list. Especially since many packages allow external linking. As opposed to the current system where all packages are just outright banned, even the helpful ones.
