Settings accessibility regressions

Posted this to the Orca list, but this list is probably a better fit.
Seems like the Settings app experienced some severe regressions under
3.26. Is this a known issue?


In particular, if I access my Sharing settings, I'm unable to tab to any
of the sharing buttons. I can't, for instance, enable the built-in SMB
server for sharing files with Windows.


Can anyone advise me on how I might enable these settings via the
command line? I can't find anything via Google, nor is running
gsettings/dconf revealing any obvious things to tweak.


Thanks.
