Type parameters XML doc tags not shown properly in Intellisense

[ChrRubin]

Issue Description

When using the <typeparam> XML doc tag, its description is shown without preceding with a new-line nor its name.

Steps to Reproduce

Add the <typeparam> tag to the XML doc comment of a class or method that accepts generic types.

Expected Behavior

Type parameters should be shown just like normal parameters with the <param> tag, each on a new line with their name followed by its description.

Actual Behavior

Only the description of <typeparam> is shown on the same line with <param>.

If multiple <typeparam> tags are used they are all shown on the same line.

Also it is worth noting that <typeparamref> is completely ignored:

I am seeing other problems with xml comments. I am not sure if there are other issues for those, but I am seeing showing up garbled in intellisense. Please let me know if there is an issue already or if I should create a new, or amend this. Thanks!
