Fails when only one line switch plate

[mart-e]

To reproduce :

Make a switch plate with all switches on the same line, for instance [{a:7},""]

Result :

TypeError: Invalid attempt to iterate non-iterable instance.
In order to be iterable, non-array objects must have a [Symbol.iterator]() method.

Note that, as a workaround, using [{a:7},""], (trailing comma) works but this is not the data generated by keyboard-layout-editor.com
