How can I find out the slide layout of the current slide?

I have a presentation in Impress with existing slides. I want to know what the slide layout of the current slide is. I can see a way to set the layout of the current slide, maybe to the same layout as current, maybe to a different layout. I cannot see how to find out what the current layout is.

Impress, LibreOffice Version: 6.4.6.2
Build ID: 0ce51a4fd21bff07a5c061082cc82c5ed232f115
CPU threads: 8; OS: Mac OS X 10.13.6; UI render: default; VCL: osx;
Locale: en-CA (en_CA.UTF-8); UI-Language: en-US
Calc: threaded

In the Sidebar, choose the Properties button. Under the Layout section you will see the layout of your slide with a border.

Tested with LibreOffice 6.3.6.2 (x86); OS: Windows 6.1.
