When you have add or subtracted lines to a text-list you need to modify the
text-list's slider so that it reflects the new data.

Here's one method to do it:

    view layout [
        style updatable-text-list text-list
        with [
            update-slider: does [
                sld/redrag lc / max 1 length? head lines
            ]
        ]
        tl: updatable-text-list 300x100
            data copy system/locale/months
        button "Delete first" [
            remove tl/data
            tl/update-slider
            show tl
        ]
        button "Append now" [
            append tl/data mold now
            tl/update-slider
            show tl
        ]
    ]
