From the documentation:

Inline LaTeX is ignored in output formats other than Markdown, LaTeX, and ConTeXt.

How about other LaTeX codes?

e.g. the following Markdown files,

\begin{flushright}
testing
\end{flushright}

pandoc to html becomes

...
<body>
\begin{flushright}
testing
\end{flushright}
</body>
...

Why wasn't it be removed form the HTML output as well, even -R is not used?

When I try this input with pandoc -f markdown -t html, I
get an empty file. Are you seeing something different?
What pandoc versionL

The command I used is actually this

pandoc -f markdown+mmd_header_identifiers+abbreviations+autolink_bare_uris+mmd_link_attributes+markdown_attribute+mmd_title_block+tex_math_double_backslash -S --base-header-level=1 --toc --toc-depth=6 -N --normalize -s --mathjax -t html5 -o

I tried your bare command and it did becomes empty. I don't know where in the command I used above get it wrong. But since -R is not used I guess it is not the expected behavior?

See #1938.
With --mathjax we include raw LaTeX blocks.

I see. Can you take a look at #2758 that @yihui said the raw LaTeX block is not included in his ePub output with --mathjax?

I'm not sure what's going on there. I just tried and the
'equation' environment did get transferred over to epub with
--mathjax. So I can't reproduce what he's describing.

Sorry I closed it too quickly. Now when I think about the reason I open this issue is about an environment like this:

\begin{flushright}
testing
\end{flushright}

Then the problem is that pandoc include "too much" LaTeX environments. This is closely related to #2758, that only a certain environments should be included in MathJax output.

Quoting from MathJax documentation:

LaTeX environments of the form \begin{XXX} ... \end{XXX} are provided where XXX is one of the following:
align [AMSmath]
align* [AMSmath]
alignat [AMSmath]
alignat* [AMSmath]
aligned [AMSmath]
alignedat [AMSmath]
array
Bmatrix
bmatrix
cases
CD AMSmath
eqnarray
eqnarray*
equation
equation*
gather [AMSmath]
gather* [AMSmath]
gathered [AMSmath]
matrix
multline [AMSmath]
multline* [AMSmath]
pmatrix
smallmatrix AMSmath
split [AMSmath]
subarray AMSmath
Vmatrix
vmatrix

Probably one of these 2 issues (#2758 and #2860) should be closed since they are describing the same issue.

I'm closing this in favor of #2758. Hope that you don't mind.

IT might be worth reproducing the table and the link to MathJax documentation in the other issue.

It is already there. (and I changed the title over there to reflect the situation)
