Bug 507032

Running `plasma-apply-lookandfeel -a <THEME>` with a global theme does not update the cursor theme on screen.

It does superficially update the cursor theme, as you can see it is changed in Settings > Colors and Themes > Global Theme > Cursors.
However, the cursors on screen do not actually change from their previous look.

STEPS TO REPRODUCE
1. In the settings, change the global theme to something other than "Breeze Dark" and the cursor theme to something other than "Breeze Dark".
2. Close the settings app.
2. Run `plasma-apply-lookandfeel -a org.kde.breezedark.desktop`

OBSERVED RESULT

Observe that the cursor on screen is not from "Breeze Dark".
Check Settings > Colors and Themes > Global Theme > Cursors and observe that the cursor theme is apparently set to "Breeze Dark", but that change has not been reflected in the actual cursor.

EXPECTED RESULT
Running `plasma-apply-lookandfeel -a org.kde.breezedark.desktop` should affect the look of the cursor on screen.

ADDITIONAL INFORMATION

On further inspection, it seems that this same bug happens when changing the global theme graphically in the settings. I don't know if the graphical interface uses plasma-apply-lookandfeel under the hood, or if this bug is just present in both places.

Running `plasma-apply-cursortheme <CURSOR_THEME> && plasma-apply-lookandfeel -a <THEME>` produces the desired behaviour (where CURSOR_THEME is the cursor theme associated with the global theme THEME).
Both commands do change the cursor theme, but only `plasma-apply-cursortheme` seems to instantly reflect this change on screen.
