CSS May Not Properly Resolve [#3582564]

Overview

It is possible when using canvas the CSS may not properly resolve. I do not have CSS preprocessing enabled and came across this issue when the canvas page loads.

Proposed resolution

Patch `LibraryHooks` so the CSS path resolves by using the file url generator generate string.
