+Links sometimes do not open in a new tab
+========================================
+
+We select for "mouse-target-changed" events: When the pointer is being
+moved, WebKit tells us if it's now being positioned over a link or not.
+
+However, when a new link pops into existence right below the mouse
+pointer (without the pointer being moved), we don't get this event. When
+the user now issues a middle-click, we open the link in the same tab.
+This is wrong.
+
+Ideally, we could access a hit test result while processing the click
+event, but that doesn't appear to be possible?
+
+This bug is also present in suckless surf and GNOME Epiphany.

 Release history for lariza

+  [Fixed]
+  - Middle-click to open in a new tab has been improved. In certain
+    conditions, the user's intention to open a new tab has been ignored
+    and URLs haven been opened in the current tab.
