Imviz: Markers do not show in tiled viewer

[Jdaviz-Triage-Bot]

Reporter: pllim

Workflow to reproduce this bug:

1. Display images in Imviz example notebook.
2. Run the cell that calls imviz.add_markers(...) to add some markers. Does not matter if it is pixel or sky coordinates.
3. Click button that creates a new tiled viewer.
4. Markers still show in the original viewer but not tiled viewer.

Workaround: Click "Data" on the new viewer and check the entry that is associated with the marker name for the markers to show.

Desired behavior: Markers should appear without workaround to have a consistent behavior as default viewer.
