See PHI451. Ref T13102. DarkConsole uses an ancient inline "onclick" handler to expand the stack traces for errors.

The new Content-Security-Policy prevents this from functioning.

Replace this with a more modern behavior-driven action instead.

• Clicked some errors in DarkConsole, saw stack traces appear.
• Grepped for onclick and jsprintf() to see if I could find any more of these, but came up empty.
