プラグイン

A long conversation that renders many LaTeX formulas at once can become laggy, because the browser keeps styling, laying out and painting content that is off screen. This plugin applies content-visibility: auto to the off-screen message bodies and block formulas, so that work is skipped and the lag is reduced.

Skips offscreen chat and trajectory rows so long sessions scroll smoothly; measured row heights keep the scrollbar steady, visible content unchanged.
