Marker: update to 2020.04.04.
https://github.com/void-linux/void-packages/pull/20727

Description:
Third update attempt (https://github.com/void-linux/void-packages/pull/17168 , https://github.com/void-linux/void-packages/pull/20181).
Built and tested on x86_64. Removing mathjax seems indeed to have no effect, so Ι followed what @Piraty did. I do not know what the binary plugin does, so I relocated it under /lib.
