I can sympathize with you because cross-browser development can be frustrating at times. However, when you ship a product and only support one browser (which happens to be the browser your company makes) you're making a statement (even if it's only implicit) that you don't really care about the open web. You personally may care about the open web, and I'm glad the issue is fixed internally, but releasing a major web application with support for only one web browser is a big "fuck you" to the web.
