Description:
When moving a connector line ('Standard Connector') in LibreOffice Draw, the preview of the connector does not follow the same route as the connector finally takes when the mouse is released. Somehow the routing calculation must be different.

Additionally, the route taken by connectors is often very odd and attempts to correct the line routing (as per above) are also very temperamental.

Efficient and intuitive line routing is not a trivial topic -- quite some complex maths involved to do it properly. But it would be a big boost in the usefulness of LO Draw to have this done well -- a la Visio type functionality.

Steps to Reproduce:
1. create new Drawing
2. draw a blue box top left
3. draw another blue box bottom right
4. create 'standard connector' from bottom of top-left box to top of bottom right box. the connect should have three line segments, vertical then horizontal then vertical.
5. select the connector
6. drag the midpoint connector handle up and down.

Actual Results:
while dragging the connector, it flips to a vert-horiz-vert configuration, but when you release the mouse, it reverts to a horiz-vert-horiz connector again.

Expected Results:
the connector route should show the same whether actively dragging/moving or just displaying.
