Cool, here's a quick hack to try a similar technique with the comments in this thread (copy and paste into dev tools:

    $$('span.commtext').forEach(span => {
        const frag = document.createDocumentFragment();
        span.textContent.split(/\s+/).forEach(word => {
          const len = Math.ceil(word.length * 0.3);
          const leading = document.createElement('strong');
          leading.textContent = word.slice(0, len);
          const trailing = document.createTextNode(word.slice(len) + ' ');
          frag.appendChild(leading);
          frag.appendChild(trailing);
        });
        span.parentNode.replaceChild(frag, span);
    })
