Collectstatic errors after upgrading from 2.15.6 to 2.15.7

[jordanvs]

When running collectstatic, I get the following error (building a docker container). It appears downgrading back to 2.15.6 solves this issue.

There appears to be a jQueryUI upgrade in 2.15.7. Perhaps this is the cause. Googling the error message points to years-old struggles with URLs in jquery ui css comments. Removing those comments seems to fix that problem for people.
