Perhaps not directly applicable in your case, 
but I bypass all same-origin annoyance by uploding 
the html as a scripted string. 

I make a second file [2nd.jshtml] enclosing the whole content in:

let secondFileContent = `xxxx`;

where xxxx is the content with newlines and all.
[NB: these `` are backticks!]

You would need to escape backticks ` to \`
in the text, but they probably are not there anyway,
and also escape ${ to \${.

You can easily do all this with a .bat file or with cscript/wscript.

Then the string is available in the main page by

<script src='2nd.jshtml'></script>
<script>
console.log(secondFileContent);
</script>
