I feel it is safe now to remove it since TAB/ENTER functionalities (Basically TAB being moved out of FilePane and ENTER on selecting file/opening Directory) is handled without these lines too. I did CI test for any regression, but its look fine without this lines too.

TAB navigation is prevented by this fix https://bugs.openjdk.org/browse/JDK-4835633 where the TAB is rejected in [this](https://github.com/openjdk/jdk/blame/a81e1bf1e1a6f00280b9be987c03fe20915fd52c/src/java.desktop/share/classes/javax/swing/plaf/basic/BasicTableUI.java#L683) line.
