When the highlight code text is too large, it can cause the browser to lag and even crash

**Describe the issue/behavior that seems buggy**

When I highlight the code text is too large, causing the browser to crash, open the browser DevTools found that the plugin will be a large number of text into the dom, too much dom caused the browser to crash and crash, please ask me when I need to highlight a large number of code text what should I do to avoid this problem?

**Sample Code or Instructions to Reproduce**

**Expected behavior**

I'm testing this in the demo on the official website by pasting in a lot of code text, and I'm also having this problem, the demo page stutters and I can't do anything with it.
