Hi! The reason this happens is that clicking Clear All focuses the text editor area, which makes Extended Clipboard pane lose focus, and that's why it closes if set to Auto Close. This behavior (setting focus to editor) is much more convenient than leaving the clipboard focused because normally you will want to continue editing your document after clearing the clipboard. That's why it was decided to leave the current behavior unchanged.
