Bugfix: [Linux,macOS] PlatformNotSupportedException on FSI on overflowing content at end of terminal

[T-Gro]

This fixes#14946

Verification attempt #1:
Debugging WSL in VS.
This works except for not starting a terminal. Output is shown in VS output pane, but input cannot be entered, or I have not figured out way how.

Verification attempt #2:

This did repro using regular dotnet fsi within WSL (Ubuntu) from the SDK from me.
I then use the same on a self-built dotnet fsi.dll from my local drive.
After the fix, it did not reproduce on WSL (Ubuntu) anymore.

Proof:

FsiNotFailingWslmp4.mp4

I can currently reproduce this bug on MacOS 14.0 with Apple Silicon using the latest dotnet 8 version available from Homebrew [1].

It looks like Homebrew is building dotnet 8 from the .NET VMR repo—do we know if this patch has made it there? It looks like the v8.0.0 tag on the VMR is dated Nov 2 while this patch is dated Nov 11.
