Tip: Avoid draw.io splitting a line when you drop a shape on it

If you drop a new shape directly onto an existing connector, draw.io automatically splits the connector in two and inserts the shape into the line — this is deliberate default behavior (splitEnabled in the underlying mxGraph engine), not a bug, and there's no menu toggle to turn it off.

Workaround: zoom in, drop the shape exactly where you want it (even centered on the line), then before releasing/settling, nudge the mouse slightly away rather than releasing right on top of the connector. The shape stays where you positioned it, but the split doesn't trigger — the split check appears to depend on cursor position at release, not the shape's final placement.

This had me puzzled for ages.
