Why does ace editor load with all text highlighted and how to remove it?

All we need is an easy explanation of the problem, so here it is.

My code looks like :

$scope.aceIDEs='var hw = new function() {\n  console.log("Hello world!");\n}'

$scope.loadAceJSExample = function (_editor) {
_editor.setValue($scope.aceIDEs);
_editor.getSession().setUseWorker(false);
_editor.setHighlightActiveLine(true);
};

And:

<div class="container fade-in" style='padding: 4em;'>
<div>
      ui-ace="{onLoad : loadAceJSExample,
      onChange : aceJSExampleChanged,
      useWrapMode : true,
      theme : 'github',
      showGutter: true,
      mode: 'javascript'

    }" />

I tried calling _editor.getSession().removeMarker(); but did not help

Every time i refresh it looks like this,once i click in it returns to normal:
Before i click

How to solve :

I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.

Method 1

Use _editor.session.setValue($scope.aceIDEs); which also resets undomanager.
Alternatively you can use _editor.setValue($scope.aceIDEs, cursorPos);. where cursorPos=-1 puts cursor at start and cursorPos=1 at the end.
Or call _editor.clearSelection() after setting value.

Note: Use and implement method 1 because this method fully tested our system.
