Issue Summary

Suppose I have "Query A" that includes two chart visualizations and two table visualizations for a total of four visualizations. One of the table visualizations is the default, the other is a custom table visualization that hides certain columns and formats others. I fork "Query A" and call it "Query B".

After the fork, "Query B" is identical to "Query A" except it only has three total visualizations: two charts and the default table, but my custom table is not forked.

Steps to Reproduce

1. Make a query and add a second table visualization in addition to the default
2. Fork the query
3. Notice that the second table visualization is not included

I would expect all the visualizations to come along with the query when it is forked.
