Cancel (clicking on 'x') while import does not always cancel on first attempt

Couchbase Admin Console
=> Eventing
=> Import Function

Click Cancel or click on the 'x' / Close. The dialog will close as expected.

Click on Import Function again, and click on Cancel / 'x'. We need to click on Cancel / 'x' twice to close the dialog.

The third time, we will need to Cancel / 'x' three times to close the dialog.

Needs be made to close on first Cancel / 'x'.
