Bug 391626 [Compatibility] e4 does not implement the post-selection concept
Reported: 2012-10-11 01:26:41 | Status: verified fixed

Steps to Reproduce: 1. Create a simple html file 1: <html> 2: <head> 3: </head> 4: <body> 5: <p>Text</p> ... repeat above line 100 times 105: </body> 106: </html> 2. Go to line 105 3. Press and hold Shift+UpArrow The outline scrolls hard and hard(moving up and down). The cursor runs without block-seletion(region highlighted), and then selecting lines takes a few seconds per line. Turning off Link-with-Editor is the only workaround for now. This problem occurs on Eclipse SDK 4.2.1.M20120914-1800 Eclipse Web Developer Tools 3.4.1.v201208170345-7O7MFsPEMkBJz0wtb-ccsarPSceUIHO9iKk6XVPV Not occurs on Eclipse SDK 3.8.1.M20120914-1540 Eclipse Web Developer Tools 3.4.1.v201208170345-7O7MFsPEMkBJz0wtb-ccsarPSceUIHO9iKk6XVPV Each WTP3.4.1 is installed from juno repository and they are same on 4.2.1 and 3.8.1 of course.(I confirmed it with fc/b command also)
