Open left panel if it is closed when 'Open Signatures Panel' is clicked
Just to open the panel in the following scenario:
- Open Okular and hide the left panel (F7).
- Open a file with a signature.
- Click on the "Show Signatures Panel" button.
- The left side panel should be implicitly shown but it is not in the current code.
Thanks in advance for reviewing.
