我想使用selenium加载this webpage并等待，直到加载Mathjax.js。
from selenium import webdriver
driver = webdriver.Chrome('C:\\Users\Dung Le\\Downloads\\chromedriver.exe')
driver.get('http://www.randomservices.org/random/foundations/Measure.html')
从页面来源，我得到了
<script>var baseURL = "../"; window.name = "main";</script>
<script src="../scripts.js"></script>
<script src="../../MathJax/MathJax.js?config=TeX-AMS_SVG"></script>
能否请您详细说明如何使用以下命令实现我的目标？
