`updateColumn`: modifying column type to link leads to a broken column

After modifying the column type to "link", trying to open the column settings leads to a blank page.
This happens if you don't specify any column_data (pretty logic) but also if you specify the same column_data as for insertColumn:

"column_data": {
    "table": "Table1",
    "other_table": "Table2"
}
