In Firefox OS development, this is part of the biggest issues we have for very specific tasks. I say '"biggest" especially because it's really difficult to work around. And even when we work around we have other issues (see bug 1126391). I don't want to say this is more important than the initial issue you're trying to solve. But yes it's important. -- Julien
