plateau: [dev branch] inconsistencies when rendering of table/figure "keys" and "notes"

[ReesePlews]

the current status of the support is "keys" from tables/figures is unknown;

occasionally the key is not rendered, or the rendering is not correct (spacing issue, dropping of symbols);

when "keys" are fully supported please let us know for testing; thank you.

Thank you for noting this, this is a regression after build rewrite.
