Pipeline Chain Operator not working consistently #10835
Description
It seems that after the first use of the pipeline chain operator, there is an issue where $? is cached so subsequent use exhibits different behavior.
If you run a successful get-item ., then it works correctly again.
Steps to reproduce
"hello" && get-item foo || "there"
"hello" || "there"Expected behavior
S> "hello" && get-item foo || "there"
hello
Get-Item: Cannot find path '/Users/steve/repos/PowerShell/foo' because it does not exist.
there
[30.77ms] /Users/steve/repos/PowerShell [host-vt]
PS> "hello" || "there"
hello
Actual behavior
PS> "hello" && get-item foo || "there"
hello
Get-Item: Cannot find path '/Users/steve/repos/PowerShell/foo' because it does not exist.
there
[30.77ms] /Users/steve/repos/PowerShell [host-vt]
PS> "hello" || "there"
hello
there
