Preview's highligt-line may not work in Vim

[yuki-yano]

Problems summary

(It's working well in my environment.)

The highlight-line returned from bat is not applied when previewing grep and help in Vim.
The --highlight-line option is passed in the preview script.
When I run fzf's --preview from Vim terminal, it is displayed correctly.

Expected

Highlight-line is applied properly in all environments.

Environment Information

• fzf-preview version (package.json):v2.7.2

• OS:macOS 10.15.7

• Vim/Neovim version: Vim 8.2.3403

It's worth noting that if you set $FZF_PREVIEW_PREVIEW_BAT_THEME to an invalid theme name (case sensitive) it will fall back to ansi (which won't work)
