Blank lines in Hovers are removed

[DanTup]

• VSCode Version: 1.5 (Insiders)
• OS Version: Windows 10

This was previously raised and fixed (#10311) in Insiders, but in the last few days it appears to have come back.

Here's the text I'm sending (note: I believe list item spacing is another known issue, so ignore those):

_italic_ **bold**.

And some \`inline code\`.

Here's a screenshot from Insiders last week (good) vs Insiders yesterday (same as Stable)

@alexandrudima looks like you did some fixing in hover.css

@jrieken This was caused by c4f3544 -- I did that because I noticed TypeScript hovers were looking pretty ugly in the monaco editor.

I will refine the CSS to apply only to the monaco-editor.
