BUG: rendering PDF with ?raw=1 not showing in Chrome & Safari

[De L.1]

To my surprise I noticed that it isn't possible to embed shared files anymore by using the ?raw=1 parameters as discussed in the Dropbox Help Center.

For instance, I am not able to see the following file anymore in Chrome 56.0.2924.87 or 57.0.2987.98:

https://www.dropbox.com/s/qgauf66zeoi816i/___TEST___.pdf?raw=1

The Errors that are being thrown by Chrome:

1. Unrecognized Content-Security-Policy directive 'referrer'.
2. Failed to load 'https://dl.dropboxusercontent.com/content_link/..../file' as a plugin, because the frame into which the plugin is loading is sandboxed.

The issues currently doesn't seem to affect any other browsers like IE, Edge or FF. 
Update: Safari 10.0.3 (Mac Sierra) also seems to be affected

Are you are aware of this issue? And will it be solved?

I am getting the same error and additional errors; all our PDF documents that are using the public Dropbox link are having this problem.

1. Failed to load 'https://dl.dropboxusercontent.com/u/{REMOVED}.pdf' as a plugin, because the frame into which the plugin is loading is sandboxed.
2. Uncaught DOMException: Failed to read the 'cookie' property from 'Document': The document is sandboxed and lacks the 'allow-same-origin' flag.

Thanks for the reports! We're looking into it. I'll follow up here once I have an update.

We've had our engineers working on this and the good news is the problem has been fixed. Please try again and you should find that this functionality works correctly.

Apologies for any inconvenience this caused.

We are having issues opening ?raw=1 links in Chrome.

This was working fine up until today.

If I copy the link to the file, then change ?dl=1 to ?raw=1 and copy & paste it into my navigation bar, it continuously loads the file, but never succeeds in rendering it. I asked another person in our office to test this and they can recreate this 100% of the time just like me.

It works in Safari and Firefox, just not in Chrome anymore.

[Greg-DB]

@jdbrown It looks like this may be an issue with Chrome. With what version(s) of Chrome are you seeing this issue?

I was able to reproduce the issue with Chrome 61.0.3163.100, but it works again for me in Chrome 62.0.3202.75, so it looks like it may already be fixed in new versions.

Yea, I probably should have included the version string in my first post, sorry.

Chrome version: Version 61.0.3163.100 (Official Build) (64-bit)
