Hide versions created with "save as new version"

[Fab]

Hello,

I can't find how to hide the original version of a file, given that the new 
versions was created with "save as new version" instead of "save changes" in 
the image editor.

When I do "save changes", it is hidden automatically and I know where to 
unhide it, but if I use  "save as new version" the icon to hide/unhidde 
doesn't seem to work.

This is with digikam 7.9.0 (debian stable).

If there is no way to correct this in the GUI, is there a way to achieve this 
by modifying the database directly? I tried to remove the record in ImageTags 
table for the original image, the record that has tagid 2, but this is 
apparently not sufficient, because in that case, there is no floating icon to 
hide/unhide the original picture anymore.

Regards
