Kickoff with improper spacing

SUMMARY
After a fresh login, floating panels which are on the edge of The Panel (such as Kickoff is on the left by default) are aligned to the edge of the screen. However after The Panel defloats and floats again (either by disabling and re-enabling floating or maximizing a window) floating panels are no longer aligned to the edge of the screen (and have proper spacing).

Note that for users with Panel set to "dodge windows/windows go below/auto hide" issue won't go away by itself since panel won't defloat automatically.

STEPS TO REPRODUCE
1. Have a floating panel set to whole width of the screen (default) and Kickoff/System tray at the edges (default)
2. Login into plasma and do not open any apps
3. Kickoff/floating plasmoids are misaligned
4. Defloat and re-float the panel
5. Now Kickoff/plasmoids have proper spacing

OBSERVED RESULT
Floating kickoff/plasmoids do not have proper spacing after a fresh login

EXPECTED RESULT
Floating kickoff/plasmoids  have proper spacing after a fresh login
