Improve global panel search

The global panel search could benefit from a few improvement:

Modal search

• If you set a custom number of search results in the config or if you reduce your window height, you will have to scroll the search results with either the actual search field or the “show all results” link hidden. It would be great, if both of those action areas were always visible and the result list scrollable on its own (either overflow: scroll on the list or position: sticky on the other parts).
• After having typed in a search term, live search results are displayed. Hitting enter will navigate me to the first result although I have not yet selected anything. In this case, I would expect to be navigated to the full page search result list instead. Enter should only forward me to a result, if I first selected it via keyboard.

General information

It would be helpful to display breadcrumbs along with the result titles in order to help the users to understand what the results are about: child pages across different areas of a site might have the same title and image (think of somethings like project and news pages containing content about the same thing).

The full page search results do show the full path but – depending on the content – this can be very hard to read. A readable path (using the titles of the parents, not the slugs) and the current result’s slug would be very helpful information for both, the modal and the full page result list.
