Something between tag 0.6.4 and tag 0.6.5 is causing the history prompt to break on remote server

[bhayden53]

I have been pulling my hair out over a weird issue with the history prompt that I started seeing after a fresh install of powerlevel9k. I have tested it over several of the powerline fonts and see the same thing.

These are my prompt elements:
POWERLEVEL9K_LEFT_PROMPT_ELEMENTS=(context dir anaconda vcs)
POWERLEVEL9K_RIGHT_PROMPT_ELEMENTS=(status root_indicator background_jobs history time)

On tag 0.6.4, I see this:

On 0.6.5 I see this:

Requested details:
-zsh version: zsh 5.0.2 (x86_64-redhat-linux-gnu)
-Have tested with and without oh-my-zsh, which I normally use. Above screenshots without oh-my-zsh installed.
-P9K was installed by cloning the repo, adding source ~/powerlevel9k/powerlevel9k.zsh-theme to my ~.zshrc, and then to debug I started switching tags and checking behavior.
-I use iterm2, and in this case I am ssh'ed into a remote server.

-Behavior persists across powerline fonts, but the font in the screenshots is Source Code Pro for Powerline
-$POWERLEVEL9K_MODE is not set in my environment.
-$P9k/debug/font-issues.zsh is empty
-there are some blank icons in get_icon_names, but nothing that looks out of the ordinary.

Hi @drhay53 ,
You are using a quite old ZSH version that is not supported by P9K any more. Could you update your Shell and try again?

My mistake, I did not notice the minimum requirements for ZSH on the wiki. Unfortunately I don't have control over this on the server, and so I will have to stick with 0.6.4 until something changes.

There is still a thing you could do: The problem appears with certain colors only and the default history segment uses grey50 as background color. So, if you set POWERLEVEL9K_HISTORY_BACKGROUND='244' the problem should disappear.
