Also currently on macOS since no configuration with default font is set yet.

Great job! Merging this to give it a go. 😀

@DominikBucher12 This doesn't work for me, see movie. The same problem on both macOS and iOS.

If you want to continue to look at this, I merged it to paragraph-fix.

@DominikBucher12 Actually, if I just have this in RichTextViewComponent+Alignment it behaves better than now, at least on macOS:

public extension RichTextViewComponent {

    /// Get the rich text alignment at current range.
    var richTextAlignment: RichTextAlignment? {
        guard let style = richTextParagraphStyle else { return nil }
        return RichTextAlignment(style.alignment)
    }

    /// Set the rich text alignment at current range.
    ///
    /// > Todo: Something's currently off with alignment. It
    /// spils over to other paragraphs when moving the input
    /// cursor and inserting new text.
    func setRichTextAlignment(
        _ alignment: RichTextAlignment
    ) {
        if richTextAlignment == alignment { return }
        setRichTextAlignment(alignment, at: selectedRange)
    }
}

I have pushed a MUCH shorter version of the alignment setter to the new branch. It seems to work pretty well, but please check it out too.
