What went wrong

I'm using ALEFindReference on a C++ project. The window with the list of referencing files is correctly shown, but I cannot open the selected file using "enter" or "t": nothing happens.

Reproducing the bug

1. I open a cpp file
2. I use ALEFindReference on a class method or class name
3. The list of file referencing that method is shown in split mode
4. Selecting one of the file and pressing "enter" or "t" nothing happens

Expected behavior:

• The selected file open in the bottom window (pressing enter) or in a new tab (pressing t), immediately closing the preview window
