Steps to reproduce
This is a sub-issue of #25242.
The cmdlet Split-Path does not respect explicit $false values for the -Qualifier, -NoQualifier, -Leaf, and -IsAbsolute switch parameters.
PS> Split-Path -Path 'C:\Windows\System32\notepad.exe' -Qualifier:$false
PS> Split-Path -Path 'C:\Windows\System32\notepad.exe' -NoQualifier:$false
PS> Split-Path -Path 'C:\Windows\System32\notepad.exe' -Leaf:$false
PS> Split-Path -Path 'C:\Windows\System32\notepad.exe' -IsAbsolute:$falseExpected behavior
PS> Split-Path -Path 'C:\Windows\System32\notepad.exe' -Qualifier:$false
C:\Windows\System32
PS> Split-Path -Path 'C:\Windows\System32\notepad.exe' -NoQualifier:$false
C:\Windows\System32
PS> Split-Path -Path 'C:\Windows\System32\notepad.exe' -Leaf:$false
C:\Windows\System32
PS> Split-Path -Path 'C:\Windows\System32\notepad.exe' -IsAbsolute:$false
C:\Windows\System32Each parameter with :$false should behave the same as omitting the switch, returning the parent directory path.
Actual behavior
PS> Split-Path -Path 'C:\Windows\System32\notepad.exe' -Qualifier:$false
C:
PS> Split-Path -Path 'C:\Windows\System32\notepad.exe' -NoQualifier:$false
\Windows\System32\notepad.exe
PS> Split-Path -Path 'C:\Windows\System32\notepad.exe' -Leaf:$false
notepad.exe
PS> Split-Path -Path 'C:\Windows\System32\notepad.exe' -IsAbsolute:$false
TrueEach parameter with :$false behaves the same as specifying the switch with :$true, incorrectly applying the switch's behavior instead of ignoring it.
Error details
No error is thrown. The cmdlet executes but ignores the explicit $false values.
