BUG ID: 74775 WebKit editing throws exception when monochrome color dragged onto text
STEPS TO TEST:
TEST PASS: If the color changes to the desired gray, and the drag appears to be accepted, the test passes.
TEST FAIL: If the color change does not apply to the text, and the drag appears to bounce back, then the bug is probably occurring. The bug can be confirmed by looking for evidence of an uncaught exception in the system console log.
