When composing a new question iver in math.stackexchange, some symbols need an extra \
(backslash) to be rendered correctly:
$ \} $
will not be rendered and needs an extra\
for preview, i.e.$\\}$
is required. Same applies to\{
.$ \| $
will be rendered as|
instead of as "parallel" and also needs an extra\
to be rendered correctly.$\!$
is rendered as!
, not as a backthinspace. Similarly,$a\,b$
is rendered asa,b
, not as a thinspace between $a$ and $b$.\\
in environments like\begin{align}...\end{align}
don't work, i.e. they don't generate a line break.
Test (one backslash): $ \{ \| \} $ (bogus)
Test (two backslashes): $\\{ \\| \\} $ (rendered as expected in preview)
As far as I remember, I already hit this issue some time ago and was confident that it would be noticed and swiftly fixed, which sadly wasn't the case...
So are there any plans to fix this? Or do they require a local (client) work-around?
According to this answer, the fix is to put spaces around the symbols and / or around math mode and non-math parts; but that doesn't seem to have any effect.
And as you can infer, the same issue is present here on Meta.
This happens only with questions and only with the preview.
And as it seems, both Meta and MSE are affected.
