Nested markdown lists not correctly displayed in hover tooltip

[rH4rtinger]

Describe the bug

Having a nested list in a markdownDescription in a JSON schema does not display the tooltip correctly when hovered over the property.

{
    "$schema": "http://json-schema.org/draft-07/schema#",
    "type": "object",
    "properties": {
        "foo": {
            "type": "string",
            "markdownDescription": "\n\nField foo\n* `a`; has childs:\n  * `b`; some text\n  * `c`; some other text\n"
        },
        "bar": {
            "type": "string",
            "markdownDescription": "\n\nField bar\n* `a`; has childs:\n\t* `b`; some text\n\t* `c`; some other text\n"
        }
    }
}

When having a new file that is using the above json schema and you press Control + Space to see your properties, the list looks correct.

However, if you used the property and hovered over your property or let you show your documentation via shortcut, the nested list no longer looks correct

It is no longer a nested list. Only the top level elements are displayed correctly.

Expected Behavior

I expect that the hovered list is the same as the Control + Space list and to see the correct nested list

Current Behavior

When hovering a property the nested list is not displayed correctly

Steps to Reproduce

1. create a json schema as above
2. link the schema to an file
3. add the property foo and hover over its tooltip

Workaround

By using \t instead of spaces (property bar), it will display in both ways correctly. However, tabs are not always common to use
