I should note: rniwa and I looked at this further and found that all of our tag-based collections (documents.images, documents.objects, table.rows, etc.) all invalidate on any element addition/removal.

Fixing this would be a rather large endeavor, but is a huge win here, and likely a reasonable win for many pages.
