Also, html code element edits text properly (no state, just refs which
prevents cursor jumping).

Thanks!

This way the popup really floats, avoiding being caught up in absolute
divs with limited width etc.

Instead, add it to removed node ids and hide them via transformed graph
functionality.

However, graph still needs to be refreshed after this is done.

This affects forceatlas etc -- nodes/edges are not hidden anymore but
really removed from the graph.

I.e. neighbor badges are clickable now.
