Markdown code blocks in JSDoc result in being prefixed with * in hover popups when inspected

[KrofDrakula]

Possibly related issue: #43783

This issue relates to the indentation and content of code blocks in JSDoc comments using Markdown formatting for code blocks in the body of a description for any type, interface or function.

Version: 1.28.2 (user setup)
Commit: 7f3ce96
Date: 2018-10-17T00:23:51.859Z
Electron: 2.0.9
Chrome: 61.0.3163.100
Node.js: 8.9.3
V8: 6.1.534.41
Architecture: x64

Steps to Reproduce:

1. Write the following annotation in a TypeScript file:

/**
 * This function just works.
 * 
 * Example:
 * 
 * ```js
 * myFn('hello');
 * ```
 */
type Fn = (arg: any) => void;

2. Hover over the Fn type name to get the JSDoc hover popup:

3. Notice that the code block is prefixed with * for every line of code.

Per JSDoc, all the lines should have the indentation and * stripped from content before passing it to the Markdown processor. This would align the tool with all other documentation tools and would avoid showing the * characters preceding every JSDoc code block line.

Does this issue occur when all extensions are disabled?: Yes
