Bug 150916 – Web Inspector: ⌥⌘C sometimes ends ups up opening inspector without console prompt focused

• Component: Web Inspector
• Status: RESOLVED FIXED

[Joseph Pecoraro]

* SUMMARY
⌥⌘C sometimes ends ups up opening inspector without console prompt focused.

* STEPS TO REPRODUCE
1. Open this page
2. Develop > Show Error Console (⌥⌘C)
  => Console prompt not focused

* NOTES
- It appears as if even though we explicitly focused the console prompt it was getting blurred later
- It looks like when the document becomesFirstResponder it sets the initial focus element, after blurring whatever was focused
