Summary0002183: Mesh View . Use Bounding-Box Not Working For Flat Lines
DescriptionUse bounding-box for highlighted or selected meshes not working for Mesh view when Display mode is set to Flat Lines. Nether pre-selection or selection bounding-box shows. It does show in all other display modes.
Steps To ReproduceGoto Edit > Preferences > Display > Mesh view, and check on the "Use bounding-box for highlighted or selected meshes".

Create or load a part, a basic solid will do, Sphere works well.

Hovering the mouse over the part or clicking on it gives you a bounding box, pe-select or select.

Select the mesh and change it's Display Mode.

The bounding-box works for Shaded, Wireframe, and Point, but does not work for Flat Lines.
Additional InformationIn version 0.14.3705, selected mesh shows bounding-box in Flat Lines display, but there is no pre-select. From 0.15.4671 release on to 0.16.5171 development, there is no pre-select or selected bounding-box.

The selection node (class SoFCSelection) reverts the pre-selection when the same instance is used multiple times in the graph. For the Flat & Lines mode this was the case.
The solution is to use an additional group node to keep the mesh data and use this as replacement for the selection node.
