Correct color extraction on App Widget drop.
Disable color extraction on drop until the workspace is back to its
normal size, then re-enable it and force re-coloring. This needs to
happen if the drop is on the workspace, but also if the drop is on the
secondary target.
Fix: 192354264
Test: Manual, see bug for details.
