Mathematical expressions in some webpages (e.g. wikipedia) are not displayed properly if I use Microsoft Edge. We can visit the following link, for example.

https://en.wikipedia.org/wiki/Equation

Compare the following picture (Microsoft Edge)

In Edge, we see that equations are truncated. I have no problem if I use Internet Explorer or Google Chrome. On the other hand, math in Stackexchange is displayed properly in Edge. Is this a problem of the browser or the webpage? Are there any solutions?
