fix: retain radio/checkbox elements in compact snapshot tree (#1008)

compact_tree() checked for "[ref=" to identify lines worth keeping, but
radio and checkbox elements render as e.g. [checked=false, ref=e1] where
the "[" opens before "checked=", not "ref=". Dropping the leading bracket
so the check is just "ref=" fixes the match for all elements with refs.

Fixes #1006
