wpress: convert 9 lines to 9 bullet points

Context — Suppose you have 9 lines without spacing in between. You want to convert them to 9 bullet points.

Problem — in Visual editor, I select the lines, and click the bullet-point (or the numbered-list) button. Only 1st line becomes an item.

Solution —

1. Do it in Text mode.
2. Then switch to Visual and you will see the 5 lines with too much line spacing in between. Good progress.
3. Now copy paste to Text mode with the line spacing. Good progress
4. Switch to Visual and you will see the line spacing reduced to single
5. Hit the same button.
