Powershell v7.1 - Invoke-WebRequest not clearing in script when using Clear-Host
See original GitHub issueAfter upgrading my script to from Powershell 7.0.3 to 7.1 whenever I use invoke-webrequest and do a clear-host it still leaves the following data in the console.
Web request status Web request completed. (Number of bytes processed: 9738485)
This is a part of a larger script that is proprietary, I removed some info from the script for privacy but the example I provided should provide enough insight into the issue. Anywhere an invoke-webrequest is used, this issue occurs, I just used Ethr as an example.
Steps to reproduce
Function Build-Menu (){
Param(
[Parameter(Mandatory=$True)][String]$MenuTitle,
[Parameter(Mandatory=$True)][array]$MenuOptions
)
$MaxValue = $MenuOptions.count-1
$Selection = 0
$EnterPressed = $False
Clear-Host
While($EnterPressed -eq $False){
$MenuTitleLength = ($MenuTitle | Measure-Object -Character).Characters
if ($MenuTitleLength -eq 16) {
$Space = 7
}
if ($MenuTitleLength -gt 16) {
$Difference = ($MenuTitleLength - 16)
$Space = (7 - $Difference)
} else {
$Difference = (16 - $MenuTitleLength)
$Space = (7 + $Difference)
}

Expected behavior
Launch script, select "Use Ethr" downloads file, clears screen, and builds a new menu. (This is from PWSH v7.0.3)
Actual behavior
Launch script, select "Use Ethr" downloads file, screen doesn't fully clear and menu gets messed up. If you press any keys it expands the window (seen in screenshot 3).
