no horizontal scrollbar in listview

[djobet]

Bug Description

When a list view has an item which does not fit horizontally, no horizontal scrollbar is shown.
It's possible to alleviate a little bit the problem by putting the ListView into a Scrollview first but

• one has to manually compute the viewport-width
• the vertical scrollbar of the listview is now available only when scrolling horizontally to the end (that's because we're scrolling the scrollview and not the listview)

Reproducible Code (if applicable)

export component App inherits Window {
    ListView {
        for t in [
            "small line",
            "small line",
            "long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, long line, ",
            "small line",] : Text {
            text: t;
        }
    }
}

Product Impact

Trying to build a chess pgn reader where move variants are showed in a tree.
Long variants are not visible, so yes it's pretty blocking.
