From 2a3e11d32d32abcf9f657c9cb58fd569e88cf3be Mon Sep 17 00:00:00 2001 From: Brian Ford Date: Mon, 26 Oct 2015 13:57:41 +0000 Subject: [PATCH] fix(router): respect LocationStrategy when constructing hrefs in links Note that this introduces more behavior for LocationStrategy which needs yet more refactoring to test.
