tab completion glitch with multiline prompts

[nhooyr]

• Have you checked if problem occurs with fish 2.4.0?
• Tried fish without third-party customizations (check sh -c 'env HOME=$(mktemp -d) fish')?

fish version installed (fish --version): 2.3.1

OS/terminal used: macOS 10.12.2, iTerm2 3.0.13

1. sh -c 'env HOME=$(mktemp -d) fish'
2. funced fish_prompt
3. Append echo -e \n at the end of the function
4. Type some gibberish into the command like dsaiojadsiojdsiaolzmxnwiewrti, make sure it is enough text so that it extends past the prompt above.

5. Press tab to complete.

if the prompt is single lined, the above glitch does not occur.

nice find

Also, it's using fish_color_search_match to highlight.

I can't reproduce this in fish 2.6.
@nhooyr, do you still have this problem?

The only time I can see something similar is when entering long gibberish and pressing Ctrl-C.

Edit: the problem with Ctrl-C already has a separate issue: #3537

Can still reproduce fine on 2.6.0

Any news here?
I can still reproduce this with fish 2.7.1 (and master) on iTerm2 and Terminal.app.
