Restoring state from existing state on start up is not working

[killyosaur]

If you come into a page with a state that is predefined (say a set of user settings), several settings, such as the width, scroll, and the open state on groups, are not restoring correctly. Some of the settings restore correctly (pinned state, column order, grouping, filters), but the remainder come in only after clicking the restore button, if at all.

EDIT: Apparently I dropped a private plunk on here, let me try that again:

Updated this issue with a public plunk so you can see the issue.

The only way I could solve this is by doing this:

Basically you need to add a delay before restoring the state.

It works.... but it is obviously not very good, since there is no way of knowing what the delay should be, and making the delay long (like 3 seconds) maked messes up the user experience.

So what is the solution? When is it safe to restore state?
