When form contains #vertical_tabs and the tabs are located within the parent without the usage of #group they will not show up. In order for tabs to be displayed at least one tab has to have #group specified. I think this can be related to #601644: Vertical Tabs requires group to be specified before tabs → .

    Can confirm the behaviour in 13 still present in Drupal 10.

    Found #1856178: '#group' Form API property only works with

    elements → which appears to relate and down the rabbit hole further we have #1168246: Freedom For Fieldsets! Long Live The DETAILS. → .

    This details a solution that includes 'Use details everywhere we're (ab)using fieldsets currently. (including vertical tabs)'

    Suggesting that perhaps vertical tabs shouldn't be used for this behaviour.

    If we look at the author example in #17 we see that the side bar where the author lives no longer uses vertical tabs.

    Grepping the core code base for 'vertical_tabs' we still see reference to vertical tabs in various places. And if we check the documentation in the comments for
    web/core/lib/Drupal/Core/Render/Element/VerticalTabs.php

    we get usage which suggests that having to specify the group and not use a child element is how these elements are suppose to work.

    Given this I think this is closed works as designed. Apologies if I have misunderstood.
