Pandoc seems to ignore math whitespace commands when the output format is docx (as viewed with LibreOffice 5.2.3.3). For example, the \qquad in the following equation is ignored:
$$ y = mx + b \qquad (1) $$
It works for LaTeX and html output.
This is a simple example: Whitespace is used for many purposes in writing equations.
Is this a bug, or am I missing something? Is there a workaround?
