Thanks!

Looks like this landed in M61, so correcting labels.

Working on a fix. The menu item was never working for incognito/guest-mode afaik, so I'm going to disable it.

[Media Router Action] Disable "Report an issue" context menu item for incognito

The menu item for sending feedback was either no-op (guest mode) or showing an
error page (incognito) before the regression that made it crash. This CL
disables the menu item for incognito and guest mode.

Rechecked this issue on Windows 10, MAC 10.12.5, Ubuntu 14.04 using chrome version 62.0.3166.0 and fix is working as intended. "Report an issue" context menu item for incognito window is not displayed.
