There is another possible work-around, at least for image output (as opposed to SVG output), taking advantage of

the Power of the Clipboard! [dun-dun-daah!]
- Select the object you want to export (I tend to group objects, that will be exported as a single image, into a single object. It’s not slicing, but it is convenient)
- Copy to the clipboard (I used the right-click context menu).

Copy to the clipboard using the Copy icon on the Actions bar
- Change to a raster-based app (I used Affinity Photo.).
I used Procreate.
- Paste it in or , preferably, create a new image from the clipboard, if the app allows you (that’s what I used in Affinity Photo). Transparency is preserved (background transparency and partial transparency of objects), and you only get the copied object, not the full layer.
The new image will appear in the Gallery.
Transparency is preserved.
- Save it from the raster app as an image.
Alternatively, export as SVG, open the SVG in Affinity Designer (as vector), and you can select objects or groups and create slices from them.
