What are the steps to reproduce this issue?

1. Make a doc comment like so

   --- ```lua
   --- -- this is a comment!
   --- 
   --- local x = 5
   --- 
   --- do
   ---  print('Hello, World!')
   --- end
   --- ```
   local x = 5

2. view the in-IDE documentation

3. cursed

What happens?

The documentation becomes this:

this is a comment!

local x = 5

do
print('Hello, World!')
end

• The leading dashes are stripped from the comment
• All indentation is stripped
• Also there's no syntax highlighting
