Feature discussion issue: #2280

Add the following markdown to the documentation for a package:

**Bold text**

*Italics*

Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum

Note the line breaks.

Expected:

1. The markdown formatting and line breaks should be rendered properly in the preview (without clicking on Show more)
2. If all the text is shown in preview mode (without clicking on Show more), then "Show more** option should not be shown to users.

Actual:

1. The markdown formatting shows properly but line breaks are removed
2. Even when all text is shown in preview mode, "Show more** option is shown.
