• Node.js: 12.8.1
• V8: 7.8.279.23-electron.0
• OS: Windows_NT x64 10.0.18363

Steps to Reproduce:

1. Create a new TS or JS file
2. Add a class with a generator method that has a leading multiline or JSDoc comment.
   • NOTE: There must be a space between the * token and the method name.
3. Place cursor at the end of the line that starts the generator method body and press enter.

Expected:
4. A new line is added with the correct indentation.

Actual:
4. A new line is added indented to the same level as the method name and an asterisk (*) is added as if this were a line continuation of a multiline or JSDoc comment.

Notes:

• This does not occur if the method does not start with a multiline or JSDoc comment.
• This does not occur if there is no space between the asterisk (*) and the method name.
• This does not occur for functions (as there is a leading function keyword between the start of the line and the asterisk (*)
• This does not occur for generator methods with a leading keyword before the *, such as static or async in JS or static, async, public, private, or protected in TS.

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

Similar to #43469 (the jsdoc comment Is required for this bug)
