[jkemper-pca]

This is based on the changes that we needed to get v7.6.2 running on our Windows environment after upgrading from v7.5

Description of Change

As done previously in another PR, the webpack code can get strings wrong when running on a Windows environment due to the use of backslashes rather than forward slashes in Unix environments. This change replaces the backslashes with forward slashes where it is required.

No need to do this. I'm going to take care of it while preparing the patch release.
