No source file or test is named. Start by reproducing the issue with the provided prompt and quote sequence, then trace PSReadLine's prompt parsing and rendering of ANSI-colored characters. Done means the green > is restored after the parser error is resolved, with regression coverage for the reported behavior.

Steps to reproduce

Define the following prompt, which prints foo followed by a green > char. (and a space):

function prompt { "foo$($PsStyle.foreground.Green)>$($PSStyle.Reset) " }

Type a single quote character, which provokes a parser error and turns the > red.

Type a closing quote to resolve the parser error.

Expected behavior

On resolving the parser error, the > should be restored with its original color, i.e. green.

Actual behavior

On resolving the parser error, the > is restored with the default foreground color.

Note that using PSReadLine seemingly does recognize the > despite being surrounded by ANSI escape sequences, but makes no attempt to preserve its color.

Note that trying something like Set-PSReadLineOption -PromptText "$($PsStyle.foreground.Green)>$($PSStyle.Reset) " does not help - PSReadLine doesn't recognize it as part of the prompt string.
