Description

From https://github.com/adobe/htl-spec/issues/92:

When multiple data-sly-attribute="${model.map}" are used on a single HTL element, only the last one is evaluated.

Given that the model and model2 have a method map that returns a String -> String map, the following HTL code will not render attributes defined in model2.map

// model1.map -> \{'a' : 'val a'}
// model2.map -> \{'b': 'val b' }
 <div
 data-sly-use.model1="com.Model1"
 data-sly-use.model2="com.Model2"
 data-sly-attribute="${model1.map}"
 data-sly-attribute="${model2.map}">
 </div>

Expected Behaviour

Expected HTML output

 <div a="val a" b="val b"></div>

Actual Behaviour

Actual HTL output

 <div b="val b"></div>
