Hey @nelsonuprety1 thanks for taking up this issue, these are my observations:

• the to/from branch is correct
• the linked issue is correct as well
• the issue correctly states the changes made and the reason to make those changes
• both the attributes integrity and crossorigin are added and with a correct sha-hash
• on manual testing there's no error generated in the browser-console
• also the babel.js gets loaded correctly, thanks for providing the screenshot of pages using the file default-markdown.html and default.html

I noticed you wanted to do default.html instead of 'default.html' (you need to use backticks the key on top of tab)

PR approved !!!
