All three paste paths (hotkey, context menu, middle-click) were sending raw clipboard text directly to the session backend via writeToSession(), bypassing xterm's built-in term.paste() which handles bracketed paste wrapping. When a remote application like vim enables bracketed paste mode (CSI ?2004h), pasted text must be wrapped in \e[200~ / \e[201~ so the application can distinguish paste from typed input. Without these markers, vim's autoindent treats each pasted newline as a manual Enter keypress, causing indentation to accumulate progressively with each line (the "staircase effect"). Now checks term.modes.bracketedPasteMode before sending and wraps the text accordingly on all paste paths. Co-authored-by: Claude Opus 4.5 <noreply@anthropic.com>
