Prompt repaint issue on term resizing, with non-empty right prompt

[blindFS]

Platform macOS

Here's what happens with ghostty:

Notice that it behaves quite differently with or without osc133

However with wezterm/terminal

Enabling osc133 doesn't help:

3 key conditions to reproduce the bug:

1. multiline left prompt string
2. none-empty right prompt
3. $env.config.render_right_prompt_on_last_line set to false

Here's what happens if condition 1 is not met:

Basically, the ideal behavior shared by bash/zsh across different prompt settings and terminal apps.

Things get more complicated if tmux enabled

With ghostty + osc133 set to true + tmux, the issue persists, just like the screenshot in #864, where text gets moved up one row at a time.
