How much AS3 is supported in Adobe Animate CC when converting to HTML5 canvas
Hello,
I was thinking of creating quiz applications in HTML Canvas format by using / taking advantage of the Toolkit for CreateJS in Adobe Animate CC 2018.
I think I've read somewhere on the internet saying that all of AS3 codes written on the Adobe animate/flash timeline are supported when exporting the Adobe Flash/Animate document to HTML5 canvas format using the CreateJS, but is it really true?
Today, I have launched Adobe Animate 2018 CC and selected New > HTML5 Canvas document.
Then I have wrote the most basic AS3 code:

/* js
stop();
*/
on the first frame of the timeline then I have published the document in Javascript/HTML format but it looks like all of the AS3 codes are ignored and the exported HTML and javascript simply plays until the end without stopping at the first frame.

I need to use some more complicated AS3 codes like the ones shown below for enabling the users to click and drag the movie clips on the stage but are these AS3 codes supported when the Adobe Animate HTML5 Canvas document is exported to HTML5 Canvas format?
