Steps to reproduce:

1. Create a new project.
2. Add two or more errors to the code so it will fail to compile.
3. Compile the project.
4. Double click an item in the errors window.

Expected result:

Item in Errors window is still highlighted in grey even though the
focus is in the text editor.

Actual result:

The original error selected is not highlighted. If there is a large
number of errors it is difficult to remember which one was the last one
you fixed since the item is no longer highlighted.
