Script tags not reported -- error thrown in content script

[gorhill]

I found a page which had five script tags in the source, but none of these were reported in the matrix: http://eligrey.com/demos/FileSaver.js/?.

Cursiously, there was no document.scripts property, which caused an error to be thrown when trying to access the document.scripts.length property. I say "curiously" because as per https://developer.mozilla.org/en-US/docs/Web/API/document.scripts, my understanding was that the document.scripts property was always present -- though maybe empty.

Well not in the DOM of this web page.

Fix will be to use document.querySelectorAll, and be prepared to receive null.

The particularity of the script tags on this page is that their type is application/ecmascript.

Fixed locally.

However, this is interesting. webRequest.onBeforeRequest is not called for these script tags present in the source:

<script type="application/ecmascript" async="" src="Blob.js"/>
<script type="application/ecmascript" async="" src="canvas-toBlob.js"/>
<script type="application/ecmascript" async="" src="FileSaver.js"/>
<script type="application/ecmascript" async="" src="//www.google-analytics.com/ga.js"/>
<script type="application/ecmascript" async="" src="demo.js"/>

Looks like a bug in chromium. Will report.

I'm stupid. Forgot to allow script in the matrix. doh
