Its implementation is in jquery/src/css/hiddenVisibleSelectors.js .
Rationale: this enables the usage of Bootstrap with a slimmer than the “slim” jQuery distribution, utilizing the Native Selector instead of the Sizzle selector. In my case (for the modules I use) I build jQuery with:
npm grunt custom:slim,-sizzle,-dimensions,-offset,-deprecated,-wrap,-core/ready,-exports/amd,-deferred --filename=jquery.s.js && npm grunt remove_map_comment --filename=jquery.s.js
N.B. I do not understand jQuery and I have not run any automatic tests.
