Enterprise installed networks can't actually be forgotten. The bug here is that we shouldn't show the 'forget' button.

Upping the priority on this because it exposes some unexpected behavior when a device-policy network is forgotten.

Ok, please update when fix is available for this, since M60 is already stable we should limit the scope of the change as much as we can to reduce any potential impact/side effect

Is this fix also addressing  issue 752101 ?

The fix is here, it's a pretty safe/small UI change:
https://chromium-review.googlesource.com/c/616077

It does not fix the underlying problems discussed in  issue 752101 , but it effectively solves the problem by preventing users from removing device-policy networks in the UI.

Settings: Internet: Hide/disable Forget for policy networks

This CL:
* Hides the 'Forget' buttons for policy networks since 'Forget' is
  not allowed (or for device-policy networks behavies unexpectedly).
* Disables the 'Forget' menu item (we do not remove it to avoid
  empty networks)
* Adds an enterprise item to policy controlled networks to match the
  primary network list and to make the reason for 'Forget' being
  disabled more apparent.

As verified in M60.0.3112.114:9592.90.0 stable hana and M61.0.3163.72:9765.50.0 beta peppy, the "Forget" button is not available for policy managed networks thus this issue should not happen again.
