subscript and superscript don't work for me on Jerboa

Testing some code syntax highlighting (may or may not work depending on UI being used):

fn blah(a: u32) -> Result {
  Ok(a*2)
}

function blah(a) {
  return a*2;
}

Nested (more backticks on our fence nest lesser backticks inside):

```
Example nested
```

I'm on the beta version and here are the issues that I notice. The first horizontal line make the text bold instead of making a line. I think that you cannot "close" a subscript or a superscript. I find the copy block button a bit too large. I think that you used the wrong spoiler tag.

Here below my test on the beta version:

!This is a spoil!<

E~x~ = x^2

Any way, I give my energy to the sync developer and testers ༼ つ ◕_◕ ༽つ

I am not yet subscribed in the Canada community in lemmy.ca, but I should ~~not~~.

You miss 100% of the shots that you don't take

Edit: The Canada@lemmy.ca link don't work. What is the proper way to link to a community in lemmy?
