[FIX] web: properties, close popover with 1 click instead of 2

Purpose
=======
When the focus is inside the label of the property, if we click
outside of the popover we need to click a second time to close the
popover.

Before that code was used to solve a bug where the definition popover
was closed when you select the text inside the property label. It
seems not necessary anymore, and it causes the issue above.
