Incorrect colors displayed in WSL

Versions

ConEmu build: 180503 & 180506 x64
OS version: Windows 10 (17677) x64
Used shell versions:

• zsh 5.1.1 (x86_64-ubuntu-linux-gnu)
• GNU bash, version 4.3.48(1)-release (x86_64-pc-linux-gnu)

Problem description

When running WSL in ConEmu, the colors seem to be mapped incorrectly. I'm running the built-in {Bash::bash} task, and double checked by resetting tasks on the latest build of ConEmu. The settings for 24-bit color and ANSI escape sequences are enabled, and the terminal mode is set to Xterm.

Steps to reproduce

1. Open a new ConEmu tab with the {Bash::bash} task
2. zsh -l -i (optional: repros in vanilla bash, but zsh is my primary shell)
3. Display colors via: 256colors2.pl

Actual results

When running the repro steps noted above:

Interestingly, if (after the steps above) start a tmux session, colors seem to diplay properly:

Expected results

When running steps 2 & 3 above directly in wsl.exe, colors are displayed as expected:

It's not clear how the linked page about 256 colours helps here -- I thought the implication from the docs is that 24-bit colour works by default?
