There is a gap between systray icons since v4.16
since I have updated to v4.16 (thanks for the updates by the way) I have an ugly gap between my systray icons. I believe it has to do with how the icons are treated. With v4.14 all icons are treated the same, v4.16 separates them in two categories.
This only happens with a two (or more) rows panel.
See attachment for more details. One picture is from v4.14, the other is v4.16
