Blend Shapes objects lack selection highlight and transform cage in the viewport

After adding Blend Shapes node and selecting one of the objects in the Layers panel there is no selection highlight nor transform cage visible in the viewport.

I think this is going to be confusing as there is still possible to change transforms with G/R/S after the Blend Shapes is added, but there is no option to do it with UI elements - it is impossible to drag a selected object with a mouse cursor for example.

Object selection visible in the viewport:

No selection visible (other then wrongly placed pivot):

No source files or tests are identified in the report. Reproduce the issue by adding a Blend Shapes node, selecting an object in the Layers panel, and checking the viewport; trace the selection and transform UI entry points. Done means the selected object shows a highlight and transform cage in the viewport, with mouse manipulation available.
