PopupFeature.js: Popup won't reopen after closing with closeBox enabled

[YXYCZXY]

When I use PopupFeature.js and enable closeBox, the popup appears when I click the icon, and it can be closed by clicking the close button. However, when I click the icon again, the popup does not appear.
start:

again:does not appear

The issue is in the hide() method in the Popup.js file, where it should clear the features.

Yes closing the popup only remove the popup but the feature is still selected and no more selectable (until an other one is selected).
It depends on the behavior you want in your app.
