fix wrapped long line copy problem on tmux

wezterm ignores wrapped long line when alt screen is used and tmux uses
alt screen that makes copying wrapped long line into multiple lines.

After testing on sevaral tui apps like tmux, w3m, htop it seems to show
reasonable performance on resizing.

Fixes #5283
