Description of the Issue

When I do a normal "find in files" search often in the results window clicking on a result line does nothing.

Steps to Reproduce the Issue

1. Put the attached file in an empty directory
2. Load it
3. Open “Find in files”
4. Search for stupiscono in *.txt (“Normal” search in all subfolders, no other checked option)
5. In the search results window you have one result line from the file (see attached screenshot)
6. Double click on it. Nothing happens.

Expected Behavior

The editor cursor goes to line containing stupiscono

Actual Behavior

Nothing happens.
If you delete lines after the matching line suddenly the double click works again. Deleting lines before the matching line seems have no effect.
In the results window, if you collapse the Search "stupiscono" section, the matching line is not collapsed and remains visible, as if it is not part of this section.
