<h1>Issue with splatting `value`</h1>

<p>
  It looks like passing an unexpected "value" to a range input via splatributes breaks on Ember < 3.17.0
</p>
<p>
	The attribute isn't set on the rendered element... Switch the dependency to 3.17.0 to see the expected 
  behaviour.
</p>

<h2>Normal input</h2>
<input type="range" value="1" name="input-1" />
<input type="range" value="1,10" name="input-1-10" />

<h2>Splatput - splatting all values onto input</h2>
<Splatput type="range" value="1" name="splatput-1" />
<Splatput type="range" value="1,10" name="splatput-1-10" />

<h2>Rangeput - splatting all values except type onto input</h2>
<Rangeput value="1" name="rangeput-1" />
<Rangeput value="1,10" name="rangeput-1-10" />

<dl>
  {{#each this.data as |input|}}
  	<dt>{{input.name}}</dt>
    <dd>Value: {{input.value}}</dd>
    <dd>Value attribute: {{input.valueAttribute}}</dd>
  {{/each}}
</dl>
