[FIX] web: list: list_activity widget popover not visible
[FIX] web: list: list_activity widget popover not visible

In edit mode, the list_activity widget popover is not fully visible
(most of it is cut). The reason is that at some point the rule
specifying that the containing list cell should have the property
'overflow: visible' became less important than another global
rule imposing the property 'overflow: hidden'.

The present commit makes sure that 'overflow: visible' is applied on all
list cells containing a list_activity widget.
