0.98: Spacing not effective in Join images Collage

[Mapaler]

XnView: MP 0.98 - 64-bit
OS: Windows 10 - 64-bit

Effect: Join images to Collage , no Spacing.
This is an old problem that has existed for several years, and I now suspect it is a bug.

To reproduce:
1.Create - Join images - Collage mode, with a Spacing.

2.The result is no spacing.

3.But Vertical mode or Horizontal mode had right spacing.

Expected behaviour: There should be spaces around the picture.
