Dope Sheet Search: Include Objects

The Dope Sheet search field currently only works for searching animated properties such as Z Location, X Rotation, custom properties etc.

This is useful for filtering properties but counterintuitive as it doesn't include the ability to also filter objects. For example a user might want to show all objects in the scene with "arm" in the object's name.

The only way of doing this currently, without selecting all said objects and using Only Show Selected (which is lost as soon as the selection changes). Is to filter by collection. Which means creating a custom collection just to achieve this functionality. This is terrible UX.

The Dope Sheet search field badly needs to include functionality for searching for objects not just properties.
