True color mode isn't enabled until something is echo'd and resets when cls (powershell)

Versions

ConEmu build: 180528 x64
OS version: Windows 10 x64
Used shell version: PowerShell 5

Problem description

After testing bug #1569 I found that this bug is fixed, but the truecolor doesn't seem to exist on the console until after something "turns it on" but I'm not sure what. If I run (Get-Gradient -StartColor 70 -EndColor 75 -Width 10) to output a color gradient (from the Pansies module) it is not in truecolor. If I run some sort of ansi sequence though, truecolor is suddenly working. This code seems to enable it:

Write-Output '�[9999S�[9999;1H'

Statements

• If I Get-Content on the 256 ansi color file that ships with ConEmu, truecolor is suddenly enabled.
• If at anytime I call Clear-Host, truecolor is reset back to 16 colors.

Steps to reproduce

1. Install the Pansies module

   Install-Module Pansies -AllowClobber

2. Run (Get-Gradient -StartColor 70 -EndColor 75 -Width 10) and you'll see that truecolor is not working.

3. Run an ansi sequence and you'll see that truecolor is working:

   get-content .\ConEmu\Addons\AnsiColors256.ans; (Get-Gradient -StartColor 70 -EndColor 75 -Width 10)

   You'll see that the output of Pansies displays true color.

   

4. Run the following

   Clear-Host; (Get-Gradient -StartColor 70 -EndColor 75 -Width 10)

   You'll see that the true color is gone

   

Actual results

Truecolor is only enabled when something outputs ansi codes, and is disabled when Clear-Host is called.

Expected results

Truecolor is enabled from the start.

This is one of the most frustrating things in my RoadMap
