I'll have a go at fixing it myself first, though I'll add a bug later if
I get stuck.


There may be a sneaky workaround for it, if you don't need
width-for-height adjustments to be used (e.g. you have a fixed column
width).

Set a clip path on the item, that doesn't actually clip it:

  GooCanvasItem *text2 = goo_canvas_text_new (table,
    "This to",
    0.0f, 0.0f,
    50.0f, GTK_ANCHOR_NW,
    "clip-path", "M 0,0 h 1000 v 1000 h -1000 z",
    NULL);

Setting a clip path turns off width-for-height adjustment for the item
so avoids the bug.
