Changing visible bodies has no effect

Plots and mesh views seem to not update while changing visible bodies on a plot that way from the display options:
``` python
with viewport.update_display_options() as opts:
assert isinstance(opts, PlotDisplayOptions)
opts.visible_bodies = [body.id for body in solution.bodies]
```
The changes only happens after interacting with the body table from the UI

Start with the viewport.update_display_options() entry point and PlotDisplayOptions.visible_bodies shown in the report, then compare that update path with the body-table interaction in the UI. Done means changing visible_bodies through the display-options context immediately updates the plot and mesh views without requiring UI interaction.
