Working vertical widgets with KDE 5 back in January

SUMMARY
KDE 6 Seems to have broken system monitor widget rendering for vertical panels.

STEPS TO REPRODUCE
1. Create a vertical panel (application menu bar, empty panel, floating or not, same result)
2. Set the width to a sane number such as 200 pixel width
3. Add a system monitor widget such as disk activity, network, etc
4. Specify a title and check "Show Title"

OBSERVED RESULT
1. The title does not appear (for at least text/line/grid/bar chart widgets)
2. For text only display styles, the labels wrap in 2 columns
3. Line charts do not show the legend or grid lines
4. Widgets seem to be compressed vertically

EXPECTED RESULT
1. Titles properly show
2. Text only widgets show a single label per row
3. Charts show legend labels and lines
