Someone anonymous has noted that the labels in two diagrams in triangle identities are misplaced. This seems clear. As the diagrams are external, can someone edit them who has access to the original code? There seem to be other errors (e.g. a C should be a D), as well.

1. Using Chrome Version 74.0.3729.157 (Official Build) (64-bit) (freshly downloaded on 2019-05-20),

Unexpected text node: ' '
or, equivalently, like so:

The "Unexpected text node: ' ' " is in a red font inside a yellow box.

Checking the page source, it looks like this page is using MathJax 2.7.1.
That was a buggy release, the current release, 2.7.5, has been out since July 2018. It looks stable and more bug free.
Maybe that's the problem?
