TYPO3 Core

When I enter a search text into the EM having selected to add extesions ("Erweiterungen hinzufügen"), then a leading or trailing space leads to an empty search. The EM should remove the leading and trailings spaces automatically from the search field entry.

Hint: First I watch at the extension list. Then I fetch an extension and copy the extension key. Then I change the select box in order to look if there has been an update. Then I paste the extension key into the search entry field. Unfortunately I did copy some blank characters at the beginning and at the end. I did not notice them. Then I wonder why the extension has not been found on the extensions from TER. However the extension is still there.
