Operating System and Browser

Tested:
Python 2.7.13
Linux sysop 4.9.0-8-amd64 #1 SMP Debian 4.9.130-2 (2018-10-27) x86_64 GNU/Linux
Windows 10

Additional Information

There's an issue in closure-library github about the file "trustedresourceurl.js" modified 17 hours ago.
"uncheckedconversions.js" have goog.require('goog.html.TrustedResourceUrl'). I think this could be some relation with the problem.

It looks like Closure team added some security checks on the use of SafeHtml (which shows up in toolbox.js). We're looking into it but not clear yet what the tool wants us to change.

[RoboErikG]

And that rule wasn't supposed to be enforced. They're working on turning it back off.

This has now been fixed on the Closure server.
