(v2) duplicated line in `split-editors` example on init

[meowgorithm]

This is likely on the Bubbles v2 side of things but when the split-editors example initializes the first lines in textarea are duplicated. This goes away on keypress.

I'm not able to reproduce using Kitty and Ghostty with/without Tmux :/

This issue occurs in v2.0.0-alpha.1 and originated from commit v2.0.0-alpha.1~24.

Before this commit, when Program was initialized with WithAltScreen(), Program.Run() would call p.render.SetMode(), which cleared the screen with ansi.EraseEntireDisplay and ansi.MoveCursorOrigin.

I believe this issue has been fixed in d727a8c on the v2-* branches.

I think #1159 is also caused by the same problem.

Yes, this seems resolved on the latest v2 alpha. Thanks @haoqixu
