The "compressed" edges do not change width when included in search result

[bestchai]

At the moment, when the edges that have been compressed (shown in the attached image) and are included in a search result do not change width so it becomes hard to distinguish whether or not they are part of a search result.

There are two possible solutions to this:

1. We can add code which also supports changing the width of the paths in the search result.
2. Or, we can make all the edges and nodes not included in the search result to have a lower opacity than the search results, and darken the edges of the search results.

The solution could be a combination of both.
