'ansi' can omit vertical bar for blockquote

[phormio]

I have a Markdown file named fruit.md:

1.  > Rhubarb rhubarb rhubarb
    > rhubarb rhubarb rhubarb
    > rhubarb rhubarb rhubarb
    > rhubarb rhubarb rhubarb
    > rhubarb rhubarb rhubarb
    > rhubarb rhubarb rhubarb.
    > Pineapple pineapple pineapple
    > pineapple pineapple pineapple
    > pineapple pineapple pineapple
    > pineapple pineapple pineapple
    > pineapple pineapple pineapple
    > pineapple pineapple pineapple
    > pineapple pineapple pineapple
    > pineapple pineapple pineapple
    > pineapple pineapple pineapple.

    Banana banana banana.

Using pandoc 3.10.2 on Linux, I ran this command:

pandoc -t ansi fruit.md

Every line of the blockquote should begin with a vertical bar, but pandoc rendered the first line without the bar:

The terminal was 145 columns wide. I mention that because of this recent comment on another bug report.
