Comment (by mreishus):

 When the customizer reflows, each section reinits and figures out if it
 should be active. It uses an incoming "active" variable but also wants to
 make sure the area "is contextually active".

 In the case of the block settings section, it thinks that it is active,
 but the is contextually active returns false, so it becomes inactive and
 collapses.
 The default definition of isContextuallyActive for a section, looks for
 controls in that section, then checks to make sure at least one is active.

 In the case of the block settings, it doesn't find any controls, so this
 section fails. This is probably because the block settings section is
 coming from Gutenberg, and this is a missing part of the integration; it
 doesn't recognize any of the controls in Gutenberg.
 so the step forward is to find out how to override isContextuallyActive
 for the block controls section, which might mean a PR to Gutenberg; it's
 possibly being added somewhere in the 'package/customize-widgets' or
 'package/edit-widgets' directories in G.
