Comment thread functionality does not work without JavaScript

[trichoplax]

Describe the bug
With JavaScript disabled, most of the interactions with a comment thread do not work:

• follow/unfollow
• tools (for moderators and admins)
• copy link
• edit
• flag

Delete works, but there is then no way to undelete because that option is in the tools menu which doesn't open.

To Reproduce
Steps to reproduce the behavior:

1. Disable JavaScript.
2. Visit a post that has a thread under it.
3. Click on the thread title.
4. See that instead of expanding (as it would with JavaScript enabled) it opens in a new page.
5. See that most of the links do not respond, or link back to the same page with no action taken.

Expected behavior
Each option that currently does not work without JavaScript should either have a fallback that provides similar functionality, or it should not be present on the page. For example, if "copy link" cannot be replicated without JavaScript, then it should not be present on the page, and it can be added by JavaScript for users who have it enabled.
