Temporary fix until the https://github.com/sir-dunxalot/ember-tooltips/pull/234 gets in

EmberTooltipComponent.js

import EmberTooltipComponent from 'ember-tooltips/components/ember-tooltip';
import { run } from '@ember/runloop';
import $ from 'jquery';

export default EmberTooltipComponent.extend({
  _hideTooltip() {
    const _tooltip = this.get('_tooltip');

    if (!_tooltip || this.get('isDestroying')) {
      return;
    }
    // NOTE:
    // This must remove listener to not compete with modal-dialogs event listener
    // SEE: https://github.com/sir-dunxalot/ember-tooltips/pull/234ß
    if (_tooltip.popperInstance) {
      _tooltip.popperInstance.popper.classList.remove(ANIMATION_CLASS);
    }

    run.later(() => {

      if (this.get('isDestroying')) {
        return;
      }

      _tooltip.hide();

      this.set('_isHiding', false);
      this.set('isShown', false);
      this.sendAction('onHide', this);
    }, this.get('_animationDuration'));
  }
});
