Prevent ConPTY from de-snapping the terminal (#13164)

This is a big hammer to put out this fire. We're keeping the hiding around for now, cause we think that's likely the one that the internal tests use that we really care about here. If we need to bring this back, we can.

* [x] Closes #13158
* [x] Closes #13162
* [x] Validated these both manually
* [x] `[Native]::ShowWindow([Native]::GetConsoleWindow(), 6)` still works
