Steps to reproduce:
1) Open the simple inline edit demo
2) Use the keyboard to place focus on the first Inline Edit field
3) Press the "enter" key to open the inline edit field
Notice that you get the invitation text, but you aren't able to get into edit mode. Cycling through the tab order and coming back to the field will work. Could have something to do with the mode that NVDA is in at the first pass through.
