Recording how to get centered Task Manager with tiny icons

SUMMARY
Plasma 5.19 introduced better panel spacers so we could actually perfectly center "Task Manager" (as it's shown at @niccolove tutorial (https://youtu.be/mlN9EeKMMsA))
However currently "Task Manager" option which is called "Maximum rows" (for horizontal panel, "Maximum columns" - for vertical) has default value "2". And with such value after adding spacers on both sides of the "Task Manager" we're getting very small icons placed in 2 rows. In order to fix this user must got to settings of the "Task Manager" and lower value of "Maximum rows" to "1".
I guess this value is some kind of legacy from very old KDE releases and currently could be safely dropped to "1" by default.


STEPS TO REPRODUCE (for vanilla KDE Plasma 5.26.1)
1. Right click on a panel, "Enter Edit Mode"
2. add 2 "Spacers"
3. Place one Spacer to left to the "Icons-Only Task Manager", second  - right to the "Icons-Only Task Manager"
Recording is attached as well

OBSERVED RESULT
Size of the Task Manager icons doesn't change and they're placed in one row

EXPECTED RESULT
Size of the Task Manager icons changes to very small they get placed in two rows

applets/taskmanager: Make 1 stripe the default

By default the taskmanager allows for applications to form up to 2
stripes, meaning 2 rows of icons. It's very easy to end up with 2
stripes when customizing your panel.

However, this is not a thing most users are used to, prefering
applications taking up to 1 row.

add an object name to the base focus scope

this is needed for appium based teststo actually expand the applet
