Although there is plenty of space on both sides of the table of the "Parameters" section when editing a host or hostgroup in the foreman UI, parameters with long names gets truncated, scrolling vertically in these input fields to reveal the names of these params is an inconvenicence, and increases risk of wrong parameter ending up associated with wrong value, as it is really hard to get an overview when you can't see from that view the overridden values mapped to their corresponding values.

Specifically the "Parameter name" field is an issue. The:

<input class="form-control" data-property="name" disabled="disabled" id="" name="" title="Parameter name" type="text" value="">

Consider for example these two smart class parameters: "multicast_address_cache" and "multicast_address_cluster": If you override both of them in your hostgroup, then scroll down to the "Host Parameters", on the left hand side, there will be two lines of "multicast_address" with rest of name truncated.
