Improve the aural interface for the toggle sections

Is your feature request related to a problem? Please describe
If a user tabs through the interactive form elements of the properties panel the aural interface is missing the context. The labels of the toggle sections aren't announced if you tab through.

You only know them if you step through each element with ctrl-option-space. If you are using the rotor in for example voiceover you also have redundant options in the form controls section without any context (Toggle section button five times and Create list item buttontwo times - if you navigate and act via the rotor you don't know which option is which) :

Describe the solution you'd like
One option for the toggle section might be a pattern that is used in the Drupal admin interface. to use the details element for each toggle section. wrapped inside the details element there could be one summary element and one div element for the form elements inside the section. aside aria-expanded proposed in #208 it might also require the aria-pressed attribute. but that way when tabbing through the toggle sections not the small toggle item gets into focus without any context but the whole detail element and the summary element provides the correct context.
