Certain errors are not shown when all experimental features are disabled

[adityapatwardhan]

When all experimental features are disabled, certain errors are not shown at all. It also seems that the "PSErrorView" experimental feature is always enabled, even after explicitly disabling it.

This does not repro in Preview.5
