Text-shadow removes rgb values when element selected

It looks like targetUpdated is run twice when the element is clicked. Once with the correct value rgb(89, 89, 89) 5px 6px 7px and a second time with rgb cleared 0 5px 6px 7px. This would explain why it's confused whether the first or last number should be interpreted as the color.

Any ideas where this second run would come from?

Yeah, I'm already aware of this issue. Unfortunately, the Style Manager parser is quite dumb and what it does is simply splitting the value by a separator, in this case ' ' (space), and distributing splits to relative properties by their order in the definition. So, technically, this change would make it work 4px 4px 4px rgb(51, 166, 58), but... unfortunately it doesn't and this is due to CSSOM inconsistency. Probably the "best solution", in this case, would be to change the text-shadow property definition but, to be honest, I'd prefer to find a more solid solution. A bit smarter parser might be a good start... so, I'm open to any suggestion/help to this issue

This seems like it could turn into a big project due to cross browser dependencies. Would it be worth bringing in a 3rd party module instead of trying to solve this inside grapes?
