We intentionally turn off a11y_checks for these click events, because the test is checking the telemetry functionality and the following 3 clicks are targeting disabled controls to test the changes in scalars (for more refer to the bug 1864576 comment 2 and bug 1854999 comment 4). Also, we are adding the test `label` to the custom widget `12foo` to satisfy the a11y_check expecting to click on a control with an accessible name. Since the test file is now passing, we are removing the `fail-if` notation that was added by the bug 1854506 before the investigation in the meta bug 1854507.
