Multi-line text allows parts of Line 2 to bleed into Line 4 (if line 4 length is shorter than line 2 length)

Reproduce the visual bleed-through with the provided multi-line function, Windows Terminal, and Oh-my-posh with TransientPrompt enabled. Trace PSReadLine's multi-line display and redraw behavior, then verify that shorter later lines no longer retain text from earlier lines while execution remains unchanged.

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest released version
• Search the existing issues, especially the pinned issues.

Screenshot

Environment data

PS Version: 5.1.22621.436
PS HostName: ConsoleHost
PSReadLine Version: 2.2.6
PSReadLine EditMode: Windows
OS: 10.0.22621.1 (WinBuild.160101.0800)
BufferWidth: 345
BufferHeight: 47

Steps to reproduce

Select multi-line text, like this one:

function Get-StrictMode {
  # returns the currently set StrictMode version 1, 2, 3
  # or 0 if StrictMode is off.
  try { $xyz = @(1); $null = ($null -eq $xyz[2]) }
  catch { return 3 }

  try { 'Not-a-Date'.Year }
  catch { return 2 }

  try { $null = ($undefined -gt 1) }
  catch { return 1 }

  return 0
}

Paste it into a session that has Oh-my-posh loaded with TransientPrompt enabled, the output is this:

[2022-10-08 15:48:44]❯ function Get-StrictMode {                                                                                                                                                                                                                                                                                                         >   # returns the currently set StrictMode version 1, 2, 3                                                                                                                                                                                                                                                                                               >   # or 0 if StrictMode is off.

Expected behavior

Output displayed as-is

Actual behavior

On line 4, the text "de is off." is repeated from line 2. I could observe this on other terminals (Windows Terminal) with multi-line text as well.

This has no impact on the execution, but is a visual bug on the terminal.
