lookandfeeltool -l / -a inconsistent (symlinked global themes)
When a plasma theme is symlinked from ~/.local/share/plasma/lookandfeel/foobar to the theme development folder in ~/src/my-theme, then lookandfeeltool -l does not list the theme, but the theme can be applied with lookandfeeltool -a foobar.
The theme works correctly, because it is shown in the "global theme settings" of KDE plasma.
So either lookandfeeltool -l should correctly symlinked themes just as "global theme settings" does, or lookandfeeltool -a should refuse to enable symlinked themes.
