[BUG] blinking after batch_load doesn't work

[eteq]

Jdaviz component

Imviz

Description

I have a common use case where I want to load a set of files, and then blink between them. If there are more than 2 files, the batch_load context manager is very useful because it can dramatically speed up loading. However, if I use batch_load, the blinking functionality for some reason doesn't work! The first image loads correctly but all the following images just show the same image (not the same as the first one, but I'm not sure what it is other than it's not a matching stretch).

How to Reproduce

1. Load a group of files using imviz.load(...) inside the imviz.batch_load() context manager
2. in the viewer, hit the "b" key to blink between at least the first 3
3. notice that everything after the first two is the same (and also seems to be in an odd stretch)

Expected behavior

Behavior of the batch loaded data should be exactly the same as if I had not done batch_load
