Using this post as a test bed. [Chrome Version 124.0.6367.207 (Official Build) (64-bit)]
I insert some in-line ##\LaTeX##: ##\frac{1}{\sqrt{1-v^2/c^2}}##. The raw text is: ##\frac{1}{\sqrt{1-v^2/c^2}}##
Press preview (and refresh the page to get MathJax rendering). Looks good so far.
You can get your ##\LaTeX## to display withour rendering by neutering the ## introducer. The most convenient way to do this is with BB code, by changing the color of one of the # signs. You can do this with the little pallete icon (above the editting window on the left, beside the Bold and Italic icons). Or, if you toggle BB code off with the "[ ]" icon, you can do it manually like this: #.
To get the BB code to stop rendering (as I did above), you can use the [PLAIN] and [/PLAIN] directives. [Generally speaking, the usual reason to muck about with this stuff is to explain how to muck about with this stuff]
I preview again after verifying that all of my quoting layers are working as expected... Yes, it still looks good.
Now I press "Post reply". The intent is to then mouse over a line containing ##\LaTeX## in this post, press quote and see what shows up when I "Insert quotes".
Stand by... editting in progress. Done.
I inserted the quote in a fresh message and copy-pasted the result into my paste buffer and then came back in to edit this post.

Yes indeed, the ##\LaTeX## has been neutered during the copy/paste operation.
##\LaTeX## (##\LaTeX##) was neutered to "LATEX"
##\frac{1}{\sqrt{1-v^2/c^2}}## (##\frac{1}{\sqrt{1-v^2/c^2}}##) was neutered to "11-v2/c2"
That has always been my experience. My practice is to reply, quoting the entire message and trim away the irrelevant content before posting.
Now to go back and repair the relativistic ##\gamma## that I initially got wrong. Done.
Edit...
I remember hearing about a way to quote ##\LaTeX## directly. And sure enough. Right click on the formula and you get a menu:
What got copied into the paste buffer was "\frac{1}{\sqrt{1-v^2/c^2}}"
Slap a couple of # signs around that and we have: ##\frac{1}{\sqrt{1-v^2/c^2}}##
If you reply to this post, you can see all of my little rendering tricks. Except for the embedded quote anyway. Nested quotes do not go into your editting buffer when replying.
