Should "change" fire if files does not change, only webkitEntries?

[inexorabletash]

From Chrome bug 360412:

If webkitdirectory is specified on an <input type=file> and a directory tree with no ordinary files is picked (or the same ordinary files but a changed directory structure) should "change" fire?

In this case files remains unchanged, although the structure exposed to webkitEntries would be modified.
