== make applyConstraints arg optional to fix webidl error ==
```
0:17.87 WebIDL.WebIDLError: error: Dictionary argument or union
argument containing a dictionary not followed by a required argument
must be optional,

>From https://heycam.github.io/webidl/#idl-operations
"If the type of an argument is a dictionary type or a union type that
has a dictionary type as one of its flattened member types, and that
dictionary type and its ancestors have no required members, and the
argument is either the final argument or is followed only by optional
arguments, then the argument MUST be specified as optional. Such
arguments are always considered to have a default value of an empty
dictionary, unless otherwise specified."
