View of digital signatures

In 5.3.6 I can see signatures, even, when they are invalid. In > 5.4.x the dialog is not shown at all.

Thank you for the report. But can you please:
- test again with new LO version if you're using some
- test with master from https://dev-builds.libreoffice.org/daily/master/ or with daily AppImage from https://libreoffice.soluzioniopen.com/.
- attach a file with invalid signature you used to get that message

Reporter sent me private PDF. I confirm "Show signatures" button and icon in the status bar don't work in master 6.2+.
Infobar is from Bug 105566. Can be that this one is about PDF or macros.

Reproducible with:

Version: 7.0.0.1
Build ID: 04ba7e3f1e51af6c5d653e543a620e36719083fd
CPU threads: 8; OS: Linux 4.15; UI render: default; VCL: gtk3
Locale: en-AU (en_AU.UTF-8); UI: en-US
Calc: threaded

Clicking on "Show signatures" in the banner, or going to "File > Digital Signatures > Digital Signatures..." does nothing.
