Selecting parent element with content collection difficult

[aertmann]

Description

Selecting element with content collections is difficult compared to the old UI.

If a content element has content collections, selecting the content element itself is difficult as the content collections lay on top.

Thus in the new UI you can select the content collections, even though they're pretty useless to select as you can't really do much with normally. The exception is if the collection is a content collection element and has additional properties.

In the old UI it content collections weren't selectable if they contain content as selecting the content allow for inserting new elements.

Steps to Reproduce

1. Insert a multi column element with content elements in the columns
2. Try to select the content element

Expected behavior

More easily select the parent element instead of the content collection.

Actual behavior

Difficult to select the parent element.

@aertmann I have here a solution which allows to select the columns and content elements in them.
But to select the multicolumn around the columns is still a problem.
