描述

Selecting text normally sets the primary selection. This is not happening within the CSS editor.

Pasting the primary selection content via middle-click, however, is working properly. The failure to set the primary selection means that I'm about to paste something other than intended.

(Copying and pasting via the clipboard works normally, but that's not what I usually use.)

研究方向
Investigate the CSS editor component in the Stylus extension (likely using CodeMirror). Look for how text selection events are handled, specifically the 'selectionchange' or 'mouseup' events. Check if the primary selection (X11 selection) is being set manually or if there's a missing call to set the selection buffer. Review the CodeMirror configuration and any custom event handlers. The issue mentions that middle click paste works but setting the selection fails, so focus on the code that updates the X11 selection clipboard.
