In the most recent two answers I have posted to Matlab answers (here, here), I have used the equation editor (Sigma, in the Matlab Answers toolbar) in my answer. The equations display correctly while I am still working on my answer, while I am using the eq.editor and after I close it, but after I submit my answer, the equation does not look right. It displays as white space or as a rectangle of pixel noise. I observe this issue when viewing my answers in Firefox and in Edge.
Some simple equations display correctly.
Here are examples, in pairs. The "A" version the text I enter in the editor. The "B" version is the equation, actually composed in the editor. For me, eq.1B displays correctly, but eqs. 2B and 3B display as white space only.
b_0=a_0+a_1+a_2 (eq. 1A)
(eq. 1B)
x=\frac{-b\pm \sqrt{b^2-4ac}}{2a} (eq. 2A)
(eq. 2B)
y_1(k)=b_0x(k)+b_1x(k-1)+b_2x(k-2)-a_1y_1(k-1)-a_2y(k-2) (eq. 3A)
(eq. 3B)
Has anyone else noticed this or have a solution? Thank you.

My recent comment in this thread is showing the equations formatted correctly. Which is differen than my OP, where the equations did not, and still do not (at least for me), display correctly. I don't know if the difference is because I cleared by browswer cache before submitting the comment, or because the problem happens with answers and OPs, but not with comments. Below, I will answer my own question - something I wouldn't normally do. This will help me know if the problem is fixed, for answers as well as comments.
@Torsten opened my answer here to edit it, then closed it, and that fixed the problem: the equations in that answer display correctly now. Thank you @Torsten.
Another test just to reasure myself that things are working better now...
quadratic formula

The equations display correctly in the answer I just entered below.
My guess is that clearing the browser cache fixed the issue.
Thank you for your help, @Torsten and @Matt J. I would Like your comments and accept an answer if I could.

Answering my own question, in order to check whether equations which I enter in an answer are displaying correctly now. I have already seen, twice, that equations which I enter into comments are displaying correctly.
quadratic formula
difference equation
