on click

This patch will solve the on click problem of Olivero theme of drupal 9.5.9

@Lingamurthy
I did not find issue on drupal 9. We_megamenu version is 8.x-1.16.
Can you write debug steps?

@hristos
If issue is only on Drupal-8 then it should updated to Drupal-9 due to Drupal-8 is not supporting now.

Please reopen if the issue still persist
