[BUG] defaultcolors not applied when using addModelsAsFrames

[dsvatunek]

Describe the bug

When using

viewer = $3Dmol.createViewer("Model", {defaultcolors: $3Dmol.elementColors.Jmol});

the color scheme gets applied to models added using

viewer.addModel(xyz_data, "xyz");

but not when using

viewer.addModelsAsFrames(xyz_data, "xyz");

To Reproduce

This code gives the default color for the nitrogen atom

<div style="text-align: center;">
        <div id="Model" style="width: 500px; height: 500px;"></div>
</div>

<script>
  $(document).ready(function() {
    var viewer = $3Dmol.createViewer("Model", {defaultcolors: $3Dmol.elementColors.Jmol});
    var xyz_data = `1
test
N 0.0 0.0 0.0
1
test
N 0.0 0.0 0.0`;
    viewer.addModelsAsFrames(xyz_data, "xyz");
    viewer.setStyle({}, {stick: {radius: 0.15},sphere: {scale: 0.25}});
    viewer.zoomTo();
    viewer.setViewStyle({style: 'outline', color: 'black', width: 0.02});
    viewer.render();
});	
</script>

While using addModel gives the correct jmol color:

<div style="text-align: center;">
        <div id="Model" style="width: 500px; height: 500px;"></div>
</div>

<script>
  $(document).ready(function() {
    var viewer = $3Dmol.createViewer("Model", {defaultcolors: $3Dmol.elementColors.Jmol});
    var xyz_data = `1
test
N 0.0 0.0 0.0`;
    viewer.addModel(xyz_data, "xyz");
    viewer.setStyle({}, {stick: {radius: 0.15},sphere: {scale: 0.25}});
    viewer.zoomTo();
    viewer.setViewStyle({style: 'outline', color: 'black', width: 0.02});
    viewer.render();
});	
</script>

Expected behavior

defaultcolors should be applied to models added using addModelsAsFrames
