We already have several attributes that are immutable but don't throw or
anything when they're changed.
e.g. <script src>, <html manifest>.
In the case of manifest, we omitted the IDL attribute to signal that it
shouldn't be changed.
As another example, <input type> was immutable in old IE and that made
people think of it as immutable.
