Workspace switcher ignores rows when in horizontal panel and showing miniatures.
Debian 11, XFCE 4.16 xfce-panel 4.16.2-1 Intel i5-11400 UHD Grphics 730 with two monitors connected via DP and HDMI.
When I add a workspace switcher to the vertical panel it works perfectly. But in a horizontal panel only button mode is usable. In miniature mode all workspaces are stacked vertically in one column. The applet in this situation does not react to setting of the number of rows - it uses as many rows as the number of workspaces always. Width of the applet in this mode seems to be random - sometimes is very wide sometimes drops down so that wokspaces seem to be reproduced proportionaly (although with very small height because stacked in one column).
Horizontal pannel single row set but 8 workspaces stacked in single (unreasonably wide) column - WRONG:
The same after few changes of the number of rows forth and back - also WRONG:
In vertical panel everything is OK:
In horizontal panel but with buttons is also OK:
