Such as margin-block, margin-inline, padding-block, padding-inline, and also some CSS functions like calc, color-mix.

The margin and padding selectors are now implemented in the development branch: https://github.com/octfx/mediawiki-extensions-TemplateStylesExtender/commit/d7e525b7af26896c586be2ac30e7a51a4773be6b

calc should already be usable without TSE.

I've put color-mix on my todo, and will look at it later
