Error when @State parses attribute in template

[steveblue]

When naming an attribute with - Readymade throws an Error. This doesn't happen whenever an attribute contains a dash, only in certain scenario(s) like below.

    <t-market theme="is--dark"
              background="url('/asset/img/act_w_talk.jpg')"
              background-repeat="no-repeat"
              background-size="100% cover">

^^^ Error happens with background-repeat="no-repeat".

The error originates in the template of a component that uses @State, however state is not being used to set the property.
