Users can now use the attachment button in chatter even when the search panel is open. This removes an unnecessary interruption and makes it easier to add files without changing context.

**Current behavior before PR:**

currently attachment button is disable while search is open in chatter. because it was disabled by opening search action.

**Desired behavior after PR is merged:**

improved logic to enable attachment button while search action is open in chatter.
