描述

Every time command is executed whole content of editor is repainted. This gets problematic if you have huge content and other non-text elements.

You can check it out using paint rectangles in chrome

And try setting bold (Ctrl + b) on some paragraph with scribe or without

研究方向
Investigate the paint rectangles in Chrome DevTools to identify which DOM elements are being repainted on command execution. Examine the Scribe command handler code to understand how editor content updates are triggered. Look for opportunities to batch updates or use more targeted DOM manipulation to avoid full layout recalculations.
