Data directories dialog (0.48.0) forces adding subdirectory instead of intended directory

When installing https://gitlab.com/vtastek/omwfx-shaders and using the new data directories dialog to add the path necessary - in my case, "C:/GOG Games/Morrowind/Mods/omwfx-shaders-main", I always get this dialog offering to add the "/shaders" subfolder instead:

If I instead select the parent folder .../Mods, the dialog shows the same path - skipping straight to .../Mods/omwfx-shaders-main/shaders. I'm guessing the dialog attempts to detect subpaths that contain mods, but fails - .../Mods/omwfx-shaders-main is the correct one to add.

As far as I can tell, this makes it impossible to install these without going back to adding the correct path to openmw.cfg manually, like usual.
