FileMaker Server 13v5 breaks interactive PDFs
Description of the issue
The update to v5 has caused interactive PDFs to no longer show up. PDFs set to show as images still show however. If you open the browser's error console you'll see 400 errors for the request of the PDF file.
If you set the container field to be non-interactive it will show, and if you connect to the database using FileMaker Pro then the interactive PDF works fine.
Steps to reproduce the problem
Create a layout with an interactive container containing a PDF. Connect to the database via WebDirect and go to the layout.
The interactive PDF should display.
The container shows only grey. This is the same grey that temporarily shows up right before the PDF is displayed when using FileMaker Pro.

The errors originate from the PDF being requested via a GET request from content.js
