Current behavior
If the calendar is used in touch ui mode and the button bar, when the clear button is clicked, the overlay is not removed. I made a workaround in my component. Remove the overlay with jQuery, but then, when I select a Date, an error appears in the console when the component tries to remove the overlay.
Solution:

$('.ui-widget-overlay.ui-datepicker-mask.ui-datepicker-mask-scrollblocker').remove();

Error:
ERROR DOMException: Failed to execute 'removeChild' on 'Node': The node to be removed is not a child of this node. at Calendar.push../node_modules/primeng/components/calendar/calendar.js.Calendar.disableModality (http://localhost:4200/vendor.js:111949:27) at http://localhost:4200/vendor.js:111218:27 at ZoneDelegate.push../node_modules/zone.js/dist/zone.js.ZoneDelegate.invokeTask (http://localhost:4200/polyfills.js:2768:31) at Object.onInvokeTask (http://localhost:4200/vendor.js:62292:33) at ZoneDelegate.push../node_modules/zone.js/dist/zone.js.ZoneDelegate.invokeTask (http://localhost:4200/polyfills.js:2767:60) at Zone.push../node_modules/zone.js/dist/zone.js.Zone.runTask (http://localhost:4200/polyfills.js:2540:47) at push../node_modules/zone.js/dist/zone.js.ZoneTask.invokeTask (http://localhost:4200/polyfills.js:2843:34) at ZoneTask.invoke (http://localhost:4200/polyfills.js:2832:48) at timer (http://localhost:4200/polyfills.js:4626:29)

Expected behavior
When the clear button is clicked, the overlay must be removed.

Minimal reproduction of the problem with instructions
<p-calendar [(ngModel)]="date" appendTo="body" dateFormat="dd/mm/yy" [touchUI]="true" [showIcon]="true" showButtonBar="true" baseZIndex="1051" (onClearClick)="removeDateFilter('start_date')">

What is the motivation / use case for changing the behavior?

Please tell us about your environment: Windows 10, Visual Studio code, webpack, node 9.8.0, npm 5.6.0.

Ok, I just see the Pull request #7175 and the disableModality() method. I don't know if this feature goes with next release. I keep this issue open until a collaborator confirm it. Thanks.
