🕗 Version & Regression Information

- This changed between versions ______ and _______
- This changed in commit or PR _______

• This is the behavior in every version I tried, and I reviewed the entire FAQ for anything that might be related to this
• I was unable to test this on prior versions because this is not a regression in typescript itself, it is a VSCode issue which I know, based on experience, will get moved to this repository.

⏯ Playground Link

Won't show vscode hover, so not worth pasting.

💻 Code

issue 1:

/**
 * Foo method
 * @param arg - Documentation for arg
 */
function ex1(arg: string) {
  return arg;
}

issue 2:

/**
 * Foo method
 * 
 * @param arg Documentation for arg but it ends up being long enough that we 
 *  must split it across lines to stay within max column width
 * @param arg2 Documentation for arg but it ends up being long enough that we must split it across lines to stay within max column width
 */
function ex2(arg: string) {
  return arg;
}

🙁 Actual behavior

Issue 1

The hover doc shows a bullet point when the hyphen is present (note the hover for the method itself renders properly)

Issue 2

🙂 Expected behavior

Issue 1

In example 1: The hover for arg should match what it does when there is no hyphen:

Issue 2:

The description for arg1 should appear exactly as arg2 does.

Additional information about the issue

Issue #61603 identified the first issue, but framed it as a bug related to not supporting TSDoc. Since jsdoc explicitly mentions the optional hyphen, this is not an issue specific to TSdoc. TypeScript support in VSCode should render this properly.
