It is resolved. If you look again at the bug report page, you’ll notice that the fix is targeted for the release of 5.1.1
They aren’t going to update source code on release branches without tagging it as a new version (even if it’s a minor version aka x.x.1)
If you download and compile the engine from source however, you should (probably) have no problem simply replacing the .cpp and .h files they updated/fixed and recompiling.
