Enter key doesn't set the link in 'Insert Link' and the image in 'Insert Image'

[hengly]

1.Visit the ​http://demos.dojotoolkit.org/demos/editor/

2. Insert a link by clicking 'Insert Link'.
3. Enter all the required filed in 'Insert Link' box and hit 'Enter'.
4. Note that hitting enter doesn't set the link.
5. Repeat Steps 1- 3 for inserting image using 'Insert Image'.
6. Enter all the required fields in the 'Insert Image' box and hit 'Enter' instead of mouse-clicking 'Set'.
7. Observe whether hitting enter button works or not.

Expected By hitting Enter, user should be able to set the link or the image.

Actual Hitting Enter for setting the link in 'Insert Link' or for setting the image in 'Insert Image' doesn't work. User has to mouse-click 'Set' .
