Reduced example

See attached reduction. Observed and reduced in Safari 5.0.2 / wk 533.18.1, but first observed some time ago inside FileMaker web viewers.

When applying color changes via JavaScript to an <option> element inside a <select multiple="multiple">, the element doesn't change appearance until something else forces a refresh. Examples are bringing another window or app to the front, zooming the window, or changing the size of an element.

Text color and background color changes are both affected. Reduction shows the same color changes working as expected for <ul> <li> elements for comparison.

Real-world case was 'graying out' options by toggling CSS class on the options, but was reduced to direct color changes on the elements.
