1. Open the Web Inspector
2. Go to the Elements panel
3. Show the Console
4. Evaluate something in the Console (e.g., 1+2)
5. Press the Up arrow
The line you evaluated is correctly put into the Console. But, focus is also moved up into the Elements panel, and the inspected node changes. This makes it very hard to use the Console's history feature.
