Highlighting a single kanji and pressing 削 throws TypeError

[shanrauf]

Nature of issue?

• Found a bug

Details about the bug:

When highlighting a single kanji and pressing the 削 button, this error is thrown:
TypeError: wrapSelection is not a function or its return value is not iterable

The fact that the error mentions something about not being iterable makes me think the error is related to the fact that a single kanji/word is being highlighted as opposed to a whole selection that has been parsed by the addon.
