A video demonstration of what the problem is

STEPS TO REPRODUCE
1. Place a panel at the bottom of the screen with an icon only task manager
2. Right-click on it and select Configure Icons-only Task Manager
3. In the Appearance tab make sure the Maximum rows is set to a number greater or equal to 2
4. Now right-click the panel and select Edit Mode to make the panel have a height that is less than 44
5. Open a lot of applications so you have a crowded panel

OBSERVED RESULT
Now, notice that the Maximum rows setting didn't have effect on a taskbar that is small enough.

ADDITIONAL INFORMATION
I know that this bug is really irrelevant in real life usage, but on Windows for example, if you have a lot of apps on the taskbar, it will hide some apps and show a little scrollbar so you can see the rest of them. On the other hand, in KDE, if you don't have a minimum height for the panel to create the rows, it will force all apps to be squashed.

Looks like you turned off grouping too. Grouping is our approach to making this not happen. :) If you don't want this to happen, turn grouping back on.
