GtkTreeView row does not resize if expander is made taller at runtime
With the default 16px expander size:
-GtkTreeView-expander-size to 64 px in the Inspector:
Notice how the rows' heights/vertical positions don't change at all, and the expander flows off the bottom and gets clipped.
This is also an issue in
master after making it query CSS min size for the expander; see !167 (comment 251684) for more on that.
gtk_tree_view_get_row_height() contains this comment:
* If the row pointed at by node does not have a height set, we default * to expander_size, which is the minimum height for regular nodes.
but this doesn't seem to be working as intended.
