Paste rendering settings timed out

[will-moore]

Error from demo server. Applying rendering settings from an Image to a Dataset.

If we see this a lot and it's causing issues, we could investigate making an the POST async. Does the OMERO API offer an asyn way of doing this?
Also would have to handle this in the browser and say "Try refreshing in a minute".
One way would be to use scripting service (but that's probably an overkill).
