Page preview Browser component on "Work Offline" mode makes XEclipse unusable.

The behaviour is identical to Firefox's when no internet connection is available and it enters "Work Offline" mode automatically.

After clicking a page in the navigator, a poppup message comes up saying that there is not internet connection and that you are working offline and to go to "File>Work Offline" and uncheck it after you become online.

Obviously it's because of the mozilla Browser component that is being reused by Eclipse, but it should be customized to skip this check. Otherwise, while having the "Page preview" View active, XEclipse becomes almost unusable. If you close the page preview, XEclipse can be used, but with the preview feature disabled.

Notice that I was using a locally installed XWiki instance reffered both by localhost and by 127.0.0.1. Both cases, same problem.
I also had firefox opened while testing.
