The patch in bug 1841408 does a lot of the work but I didn't want to make it bigger than necessary so there's still some work left to do.

• Add the "Pocket - Related to {keyword}" bottom text
• Don't show the description for non-top-picks
• Make sure the URL is always shown

STR for QA:

This bug implements the final Pocket UI as shown in the Figma (see "CD Work area" in the left sidebar, then the "V4 - Final" group in the main pane). Both "low confidence" (non-top-pick) and "high confidence" (top pick) Pocket suggestions should appear more or less like they do in the Figma. Expected differences:

• This bug does not implement the "Recommended reads" label above the suggestion, so it will still say "Top pick"
• The Feedback menu is expected to appear in both high and low confidence. The Figma is incorrect on this. However there's a bug where the button may sometimes not appear in the low confidence suggestion, so if it doesn't appear, don't worry about it. It's fixed in bug 1841409 and we can verify the behavior there.
• This bug does not implement all the behavior and menu items of the Feedback menu
• The separator between the suggestion title and URL is expected to be an em dash ("—") as usual, not a dot like it is in the Figma

STR:

1. Set browser.urlbar.pocket.featureGate = true to enable Pocket suggestions and browser.urlbar.bestMatch.enabled to enable best match
2. Type "breakfas" (no "t" at the end) and verify a Pocket suggestion does not appear
3. Finish typing "breakfast" (with a "t" at the end) and verify a "Cat Cora" Pocket suggestion appears at the bottom of the urlbar panel. It should have: a Pocket icon, title, URL, some text at the bottom that says "Pocket" and the full keyword that matches what you typed, Feedback button
4. Continue typing "breakfast casserole" and verify the suggestion remains in the panel. In the text at the bottom of the suggestion, the part of the full keyword that you typed should be bold, and the rest of the keyword should not be bold.
5. Clear the input and type "breakfast paninis". The "Cat Cora" suggestion should appear after you finish typing "breakfast" and "breakfast ", as before. After that, no suggestion should appear until you fully type "breakfast paninis". A top pick suggestion should appear called "Your New Favorite Breakfast Sandwich is Anything but Basic". It should have the same appearance as the "low" confidence suggestion except it should also have a long description under the title.

If you'd like, you can test other keywords and suggestions by looking at the spreadsheet. See the low and high confidence keyword columns. The keywords in each column are separated by commas, and note that each keyword string can contain more than one word.

• Low confidence keywords can be triggered by typing the first word in the keyword, followed by one or more characters after that
• High confidence keywords must be typed in full
