Select-String highlighting / emphasis only works on first Select-String

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest released version
• Search the existing issues.
• Refer to the FAQ.
• Refer to Differences between Windows PowerShell 5.1 and PowerShell.

Steps to reproduce

The highlighting / emphasis from Select-String is only done for the first instance of Select-String in the pipeline. It should be the last since it is a highlighting technique.

Hello >>World<<


[C:\Users\lee]
PS:3 > "Hello World" | Select-String Hello | Select-String World

Hello >>World<<


[C:\Users\lee]
PS:4 > "Hello World" | Select-String Hello -NoEmphasis | Select-String World

Hello >>World<<

Actual behavior

Visuals

Start by reproducing the four Select-String pipeline examples from the issue and trace how emphasis is carried between successive Select-String commands. Done means the final Select-String controls the highlighting, while -NoEmphasis on the first command does not suppress emphasis from the later command.
