`<script>` element does not support `.text` property to get content

[EndlessJour9527]

Bug Description

Currently, in JSAR Runtime, the <script> element does not support the .text property to retrieve its content. For example, with the following HTML snippet:

<script id="normalScript" type="text/javascript">
  const a = 1;
</script>

Attempting to get the script content using JavaScript:

const normalScript = document.getElementById("normalScript").text;
console.log(normalScript); // Expected: "\n  const a = 1;\n"

The .text property should return the textual content inside the <script> tag, as defined in the HTML Standard. This is supported in major browsers (Chromium, Gecko, WebKit).

Expected Behavior

• element.text returns the content inside the <script> tag as a string.

Actual Behavior

• element.text is undefined or not implemented.

Reference

• HTML Standard: dom-script-text
• Chromium implementation: HTMLScriptElement::text
• Gecko implementation: nsIScriptElement::GetScriptText

Suggested Fix

Implement the .text property on HTMLScriptElement so that it returns the content of the script element.

Example

<script id="normalScript" type="text/javascript">
  const a = 1;
</script>
<script>
  const normalScript = document.getElementById("normalScript").text;
  console.log(normalScript); // Should log: "\n  const a = 1;\n"
</script>
