Bullet lists don't work when appending to a SpannableStringBuilder about markwon

Hey!

I have looked into it and it's definitely a bug. Let me explain: there is a simple check in some of the spans, something like this:

public void drawLeadingMargin(Canvas c, Paint p, int x, int dir, int top, int baseline, int bottom, CharSequence text, int start, int end, boolean first, Layout layout) {
    if (this.start != start) {
        return;
    }
}

this.start is a value that is passed by AST visitor indicating current parsing position. As there are multiple parsing operations, each line will hold own indexes (starting with 0), but when all lines are set to a TextView, TextView will pass own indexes (starting with the very first character). So, this explains why list is rendered correctly if applied first.

There is such a check in the first place in order to not draw a bullet on each line if a line is too big and was split (span's drawLeadingMargin would be called for each such line).

Thanks for the issue, I will think of what can be done with it for the next release 👍

We just got your develop branch going with our project and verified that all is well. Thanks for that.
