Issues:
- Table is not accessible (finding [2] in the Prüfbericht Barrierefreiheit GnuPG Kleopatra 3.1.20.3); in particular, the Result column is fully inaccessible
- Scroll area inside Details box shouldn't get focus
- Text in Details box is inaccessible
- Texts before table are not accessible (they are read out by ocra when the dialog is shown, but they cannot be focussed)
- Weird placement of Details box between the two check boxes; maybe move "Show all" check box before table
