== Steps to reproduce
1- Create a Tag calleg "GT" under Global scope
2- Add an arbitrary property to this tag
3- Switch to Liferay scope
4- Go to Admin/Site Administration/Content/Web Content
5- Create a new WC & tag it with GT >>> Save
6- Go to Tags under Liferay scope
Issue Note, that GT has been created under Liferay scope, but its property has not.
=== Expected behavior
Properties should be also preserved in the new scope Group.
So, here, we try to retrieve the tag, based on its name and the scopeGroupId. However, when the tag comes from Global scope, it will remain NULL after the assetTagLocalService.getTag(siteGroupId, tagName);.
And as we can see, we populate the new tag with default data only within the catch() block.
