Keep highlight in correct position when opening folder

This is a minor enhancement, not very crucial.

Sometimes I just want to manually browse to a particular file that I have open in one of my tabs, so instead of clicking Reveal in Tree View, I might look at tree view to find which folder the file is in, which gets highlighted:

However, when I want to dig deeper, and click the arrow on the left to expand the shared folder, this action sets the highlight on the shared folder itself, rather than keeping it on whatever child folder the file is in:

It would be great if upon expanding a highlighted folder, the highlight could move to the child folder where the currently active file is in, e.g.:

This way, if I'm locating a file manually and an expanding sub folders, I can easily see which sub folder to dig into.
