[Bug]: Inappropriate preview line row with strategy static

[sky96111]

What did you expect to happen?

[preview]
## which preview strategy to use to calculate the preview height (respects max_preview_height).
## possible values: auto, static
## auto: length of the selected command.
## static: length of the longest command stored in the history.
## fixed: use max_preview_height as fixed height.
strategy = "static"

When preview strategy is set to static, it calculate length of the longest command stored in the history.
In its design, it is intended to display all commands as comprehensively as possible.

But not all longest command cost the most line rows, because command with line break \^J can take up more lines than command with most characters.

Proper display should be like:

What happened?

Preview area presents only 2 lines (the longest command costs), which result in command with break line character be cut.
