Pressing enter when deleting a table opens a new modal

[iriberri]

Steps:

• Select a dataset
• Click on "Delete dataset"
• Press enter 5 times
  • The system is just opening new windows. My expected behaviour is that the table gets deleted with the enter.
• Then, I try to manually click on the "Ok, Delete" button. After 1 or 2 clicks, the table gets deleted but the window doesn't close. As the system continues trying to delete an already deleted dataset:

• After this, you need to click those 5 times on the "X" button to hide the delete modal and get back to your dashboard.
