Currently, the Notifications applet closes itself when the last element (notification) is removed (or all elements are removed by pressing "Clear History" button in the top-right corner). But also it closes itself, even if the applet is pinned, and I guess that this behaviour isn't correct. D29651 <https://phabricator.kde.org/D29651> fixes this issue. Currently, the Clipboard applet remains visible when the last element (fragment) is removed (or all elements are removed by clicking "Clear History" button in the top-right corner), even if the applet isn't pinned. D29652 <https://phabricator.kde.org/D29652> makes the Clipboard applet to close itself if there are no elements in the clipboard history and it's not pinned.
