I am submitting a BUG report

Description
When the focus is on the grid menu and the user hits the ENTER button in the keyboard, the Grid menu appears on the left side of the screen.

Expected Behavior
The grid menu should open up in the screen and not at the left side.

Current Behavior
When we hit enter key with focus on the grid menu, the menu shows up on Left side of the screen. The shown menu is ONLY partially visible.

The bug is reproducible in this page

Angular-Slickgrid issue reference. The Grid Menu gets positioned on this line there's probably some code refactoring to do for supporting a keyboard event
