FuzzySelect messes up existing formatting

This is both a normal select and a fuzzy select with the same list. The selected item on the fuzzy select has messed up the formatting.

After looking a bit deeper the colorful theme seems to be showing matches as bold which messes up existing formatting.

dialoguer/src/theme/colorful.rs

Lines 376 to 381 in 731c70b

	write!(
	f,
	"{}",
	self.active_item_style
	.apply_to(self.fuzzy_match_highlight_style.apply_to(c))
	)?;

A workaround is to disable highlighting the matches:

    let selection = FuzzySelect::with_theme(&ColorfulTheme::default())
        .highlight_matches(false)
        .with_prompt("Pick your flavor")
        ...

However this also disables the active_item_style that marks the whole line in blue.

For a real fix the library should probably switch to some smarter ANSI formatting dependency that can add to existing formatting. Or make sure any existing formatting is removed before applying formatting.
