fix: skip updates when state is disabled

## Details

Issue: #208

When state is disabled the update logic is still triggered. For the most
part this doesn't really do anything as it triggers the non rendered
view. However it does hijack the window options and prevents users from
changing them by constantly changing them back.

To fix this gate the event based callbacks on state being enabled. The
only case where state is disabled in the UI is from user commands.
