I am bothered by the same issue. I am wondering if it is related to hypothesis/h#5706 but I could be wrong. Any answer and pointers would be appreciated!

I was able to reproduce in Firefox 86 but not Safari 14 or Chrome 90. It occurred when using the HTML or SVG MathJax rendering modes (this can be changed by right-clicking an equation and selecting Math Settings => Math Renderer => {Renderer}) but not the MathML mode or plain source mode.

The original page linked in this issue is no longer available. Testing on https://justinwillmert.com/articles/2020/numerically-computing-the-exponential-function-with-polynomial-approximations/ which uses MathJax, I see a different behavior. When selecting a line containing inline math rendered by MathJax, the whole line is highlighted, but the math parts are not:

(My highlights are green here because I'm testing a client feature that enables different colors for highlights. That is unrelated to the issue).

The behavior is the same whether the math rendering mode is set to CHTML or SVG. To change it, right click on any equation and select Math Settings => Math Renderer => [Choose SVG or CHTML].
