Selected file from search is not actually selected

[Enrico]

I was looking for useless files in a folder and I've used the File's search feature. It works fine, but when I search something (e.g. .SVG files) the first file on the list appears selected, but it isn't!

I've found this bug because I tried to select all the files clicking on the last one while holding SHIFT, but File selected only the item I've clicked on. I can't explain the problem very well, so I've recorded a video about this problem (see the attached file).

You can see that the first file looks selected (it's in orange), but when I click on another file holding SHIFT, the selection goes only on the file I've clicked and not on all files from the first one and the one I've clicked on.
