Description David 2021-10-05 01:31:36 UTC 
SUMMARY
If I configure the icons-only task manager to show only one row of icons, after adding a certain amount of icons (and this happens at certain fixed numbers of present icons depending on the panel size), when a new icon is added by launching an app, the icon does not show up in the panel until adding yet another more icon (from another app).

STEPS TO REPRODUCE
1. Right-click the icons-only task manager, go to 'Appearance', set 'Maximum rows = 1'.
2. Start launching many apps and watch their icons popping up in the task manager.

OBSERVED RESULT
Every time the task manager has a certain number of icons, a newly added icon will not show up until adding yet another icon.

EXPECTED RESULT
Should show all icons, always.
