Created attachment 59061 [details] Correct behavior - IE 8 When using a composition string with a partial selection range, webkit can't render the selection range correctly. It'll be ok if the selection range covers the whole composition string. See attached images: The first one is the correct behavior in IE 8, the second one is taken with a hacked chrome which supports the selection range in composition string (stock chrome doesn't support it). The third one is taken with the same chrome binary but with a full selection range.
