1. Visit the Projects page. Note the dswid param value (?dswid=XYZ) in the address bar.
2. Middle-click on one of the projects (or use the context menu to select "open link in new tab")
3. Switch to the new tab. Note the dswid param in the address bar.
New tab has a different dswid. (The tab may initially load a page with the original dswid, but if so it should redirect to a new dswid.)
New tab has the same dswid. This will lead to all DeltaSpike's window-based scopes (including GroupedConversationScoped) accidentally sharing state between tabs.
This problem can also be seen on other pages which have lists of links, including the version groups page, languages. However, middle-clicking the Projects link in the top menu, while on the Projects page, or pasting a copied URL (with dswid) into a new tab, does not reproduce the problem.
Ah: these lists of links have URLs ending in &dswid=XYZ (without a preceding '?'), because they have been corrupted by urlrewrite rules.
