Surely these are harmless though? We'd only be concerned if the parentage loop is in the same axis. > The culprit is line 179 of dynamic-align-engraver - if anyone has any > intuition as to why this is the case, lemme know! set_bound () also sets the X-parent if _this_ doesn't already have one and we're setting the left bound. Axis_group_interface::add_element () sets the DynamicLineSpanner as X-parent (depends on 'axes setting). So we get the following situation: If we acknowledge a DynamicText, set DynamicLineSpanner as Y-parent. If the DynamicText starts a new alignment spanner, set as X-parent of DynamicLineSpanner.
