[Evolution] cycle through contact editor with TAB key

[Herr Oswald <herr_oswald gmx de>]

Hello,

when I open the contacts editor window, I'd expect to be able to cycle
through all fields with the TAB key. Am my evo (3.28.5-
0ubuntu0.18.04.1), I get stuck at "sort in as", "categories", "wants
HTML emails", <2nd phone number field> and <2nd SIP address field>.

Is that desired behaviour - or is it a bug?

Cheers,
Wolf
