[BUG] Inline math in image name has rendering problem using pandoc

![$N_d$ vs $f_l$. The pulsar's DM is assumed to be 750 pc cm$^{-3}$ with a Nyquist complex-sampling bandwidth of 16 MHz.](assets/Multi-Segment%20Coherent%20Dedispersion%20Method%20Based%20on%20Overlap-Save/2.png){#fig:dispersion-smearing-time width=75%}

I am using pandoc with pandoc-crossref filter.

After updated to the newest version, the above has rendering issue.

It seems that the "{}" bracket in the inline math $^{-3}$ is causing the problem.

The newly added syntax seems causing this problem. How to disable it for pandoc parser?

Will fix it this week.
