Getting similar.

I have a row of 2 cells, each cell nominally holding a panel.Tabs widget - each Tabs widget holding 5x 3D views.

On first draw, both are fine. But one subsequent update and the other cell of the row drops out some, but not all, of the 3D views.

The data is correctly held right up to the point of re-issuing to the main row cell.

Will try and create an MRE if it helps, but a bit time-pressured at the minute.
