/**
* This files tests the 'value sanitization algorithm' for the various input
* types. Note that an input's value is affected by more than just its type's
* value sanitization algorithm; e.g. some type=range has actions that the user
* agent must perform to change the element's value to avoid underflow/overflow
* and step mismatch (when possible). We specifically avoid triggering these
* other actions here so that this test only tests the value sanitization
* algorithm for the various input types.
*
* XXXjwatt splitting out testing of the value sanitization algorithm and
* "other things" that affect .value makes it harder to know what we're testing
* and what we've missed, because what's included in the value sanitization
* algorithm and what's not is different from input type to input type. It
* seems to me it would be better to have a test (maybe one per type) focused
* on testing .value for permutations of all other inputs that can affect it.
* The value sanitization algorithm is just an internal spec concept after all.
