MXML: CTRL+Space Import in <fx:Script> block sometimes places import on very top of file

When working within a Script block within an mxml file, CTRL+Space for completion/import sometimes places the import outside of the script block as the very first line of the file.

Steps to reproduce

1. Create an mxml file with a Script block:

<?xml version="1.0" encoding="utf-8"?>
<j:VGroup xmlns:fx="http://ns.adobe.com/mxml/2009"
    xmlns:j="library://ns.apache.org/royale/jewel"
    xmlns:js="library://ns.apache.org/royale/basic"
    xmlns:html="library://ns.apache.org/royale/html">

    <fx:Script>
        <![CDATA[
            
        ]]>
    </fx:Script>

</j:VGroup>

1. Add some code that will allow auto complete

<?xml version="1.0" encoding="utf-8"?>
<j:VGroup xmlns:fx="http://ns.adobe.com/mxml/2009"
    xmlns:j="library://ns.apache.org/royale/jewel"
    xmlns:js="library://ns.apache.org/royale/basic"
    xmlns:html="library://ns.apache.org/royale/html">

    <fx:Script>
        <![CDATA[
             private var test:RemoteOb
        ]]>
    </fx:Script>

</j:VGroup>

1. Use CTRL+Space to auto complete

2. Sometimes, the import will appear at the very top of the file

Expected Results

The import appears at the top of the Script block:

<?xml version="1.0" encoding="utf-8"?>
<j:VGroup xmlns:fx="http://ns.adobe.com/mxml/2009"
    xmlns:j="library://ns.apache.org/royale/jewel"
    xmlns:js="library://ns.apache.org/royale/basic"
    xmlns:html="library://ns.apache.org/royale/html">

    <fx:Script>
        <![CDATA[
             import org.apache.royale.net.RemoteObject;

             private var test:RemoteObject;
        ]]>
    </fx:Script>

</j:VGroup>

Actual Results

import org.apache.royale.net.RemoteObject;

<?xml version="1.0" encoding="utf-8"?>
<j:VGroup xmlns:fx="http://ns.adobe.com/mxml/2009"
    xmlns:j="library://ns.apache.org/royale/jewel"
    xmlns:js="library://ns.apache.org/royale/basic"
    xmlns:html="library://ns.apache.org/royale/html">

    <fx:Script>
        <![CDATA[
             private var test:RemoteObject;
        ]]>
    </fx:Script>

</j:VGroup>

Observations

I wish I had concrete steps on how to reproduce this issue; it is quite random/sporadic. I will add notes as I learn more.

It is possible that it may be tied to other features within VSCode like auto organize imports, or auto source formatting. I use Beautify for mxml, and ActionScript Tools for AS3. I have sometimes seen worse corruption after saving once this occurs as the imports are usually considerably off the viewable screen.

If you’re interested in trying it out before I do the next release, feel free to try a nightly build.

@brianraymes Thank you again! I can finally reproduce. It seems to happen when a missing import gets added automatically, but there were no existing imports in the <fx:Script> block beforehand.
