Get-Culture's errors with -ErrorAction are not terminating errors

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

Cause an error in Get-Culture while using -ErrorAction Stop . It does not terminate.

Expected behavior

console Terminating errors should cause the function to end. For example Get-Item -Ea Stop

function funcShouldStop2 {
    # expects terminating error
    [CmdletBinding()]
    param()
    Get-Item 'somefakefilename' -ea Stop
    '⚠ Should Never Reach'
}
funcShouldStop2

No output

Actual behavior

function funcShouldStop1 {
    # expects terminating error
    [CmdletBinding()]
    param()
    Get-Culture 'en-uk' -ea Stop
    '⚠ Should Never Reach'
}
> funcShouldStop1

Get-Culture:

And the end

[SeeminglyScience]

In that case, shouldn’t this halt?

Note the wording there, it’s pipeline terminating, which works differently than call stack terminating errors. throw and -ea stop are the latter, parameter validation and PSCmdlet.ThrowTerminatingError are the former.

Note I’m not defending this behavior, but it is by design.
