ISBAT Have blocks with an attribute named Animation w/o breaking

[margolisj]

Describe the bug:

I should be able to filter blocks that I do not want being accessed via this LayoutPreview / sanitizeBlocks function Code Here. Coblocks is currently breaking our Block Previews, as we also use an attribute named animation.

To reproduce:

1. Have a non-Coblocks block that has an attribute named animation, where that attribute is expected to exist for render.
2. Have both Plugins active. Load a block preview for
3. See Error

Expected behavior:

We would expect you to be targeting only Coblocks blocks.
