Turn Restriction not displayed - Glitch in spatial index in DataSet?

[Gubaer]

How to reproduce:

1. Load the attached .osm file. It includes three nodes node 1, node 2, and node via, and two ways way 1 and way 2.
2. Create a new relation as turn restriction
   1. Add the tag type=restriction
   2. Add the tag restriction=no_left_turn
   3. Select way 1 and add it as member with role from
   4. Select way 2 and add it as member with role to
   5. Select node via and add it as member with role via
3. Save the relation

The turn restriction is not displayed in the map view.

4. Slightly move node 2

The turn restriction is displayed.

Observation: DataSet::searchRelations(bbox) only replies the new turn restriction after node 2 is slightly moved. Loooks like a glitch in the spatial index.

Here's how the relation should look like to reproduce:
