Summary:
This fixes the broken layout of the tab bar (tab bar takes the whole view)
when a panel is changed from horizontal to vertical that persists
until plasmashell is restarted.
BUG: 393888

Test Plan:
Change panel orientation from horizontal to vertical. Open Kickoff.
Before fix: tab bar fills the whole view making the Kickoff unusable even if you make the panel horizontal again.
After fix: tab bar has the correct size.
