nbconvert inline \mathbf ($\mathbf {x}$) fails to export to PDF

[frohro]

Hi,
I have a notebook with just this:
$\mathbf {x}$
When I try to export to pdf using jupyter nbconvert, I get this error:

! LaTeX Error: \mathbf allowed only in math mode.

See the LaTeX manual or LaTeX Companion for explanation.

If I put
$$\mathbf{x}$$
with two dollar signs (on its own line), it works fine.

I'm enclosing a .zip with the not-working line.

Thanks for fixing bugs!

Looking at your source. You have a space between the first dollar sign and the math inside. Remove that, and it should work. This is a known issue with how our dependency of pandoc handles the extra space around the dollar sign. That makes this a duplicate of #749. #2188 looks like it fixes this.

I confirm removing the space fixes the issue.
Thanks!
