Spreadsheet editor allows constraint-violating rows to be inserted/updated

Trying on local to update a row in a way that violates the database constraints, I get:
```
Check constraint "user_submits_non_empty_row" violated
These can be ignored using '--continue'
```
However if I create the same such updated row using the online spreadsheet editor, it allows them to be committed, pull-requested, and merged into the db with seemingly no problem.
