Firefox Clipper Doesn't Save Full Articles

OS: Windows 10 1809
Browser: Firefox 65.0.2
Extension Version: 3.8.0

Example article to save: https://www.nytimes.com/2019/03/18/technology/lyft-ipo-stock.html

Problem: When clipping in "Article" mode, the content cuts off after a few paragraphs, and I can't save the full article.
