It appears that automatic transaction should treat changing the value of
input and textarea as a "DOM change" because I can definitely see use cases
for scripts to modify the values of input/textarea in automatic
transactions and expect it be restored upon unapply/reapply.

Unfortunately, the current proposal doesn't support this because
input/textarea's value is only reflected in the shadow DOM in some UA
implementations and IDL attribute. Should we special case the value IDL
attribute of HTMLInputElement and HTMLTextAreaElement in UndoManager spec?
