Ver 3: Filtering with Collapse All does not find anything

[SteveTheTechie]

What is the current behavior?

If you attempt to find items when all optgroups are collapsed, nothing is found.

What is the expected behavior?

It should find something if it is there. Perhaps if a filter is enabled when everything is collapse, the could should maybe force all the options to be expanded.

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo

Enable the filter with a select w/ optgroups, collapse all, then attempt to filter the options.

Common options for demos are jsfiddle and codepen

If you are requesting a new or changed feature, please provide a rationale

The filtering needs to be intuitive and not confusing.

Will you submit a corresponding Pull Request to fix the bug or implement the feature?

Maybe... kind of busy now.

Please tell us about your setup

It seems like forcing everything open would make sense. Otherwise there wouldn't be a sensible way to display the results.
