By thomas-mcdonald:

Two issues here:

* Shouldn't we be calling `ie_hex_str`?
* The function doesn't actually get called regardless of whether it's with underscores or hyphens - it is simply output as `ie-hex-str(#222222)`/`ie_hex_str(#222222)`

Full output:

filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='ie_hex_str(#333333)', endColorstr='ie_hex_str(#222222)', GradientType=0);
