It would be great to have an event that fires only when a tab or details element is being shown or hidden. This would much help us solving issues like https://www.drupal.org/node/2631710 where JS needs to bind on event after details element is shown, not before.

Thanks for submitting your issue.
Feature requests have to be filled against the next minor version (or next major if they plan to introduce a BC break).

I think that kind of event does not cost much and can always be useful for many reasons (eg. a map in a [vertical]tab that'd need to be loaded/resized on shown).

I am looking for the similar thing in Drupal 7 as well. Not only vertical tabs, but also other widget built with js in Drupal does not fire any event for other developer. It would be better to take event into account during the design in future.

Drupal core is moving towards using a “main” branch. As an interim step, a new 11.x branch has been opened, as Drupal.org infrastructure cannot currently fully support a branch named main. New developments and disruptive changes should now be targeted for the 11.x branch, which currently accepts only minor-version allowed changes.
