Canon EF-M 15-45mm: focal length at 15mm set to16.9

I have an LX7 which has a trick sensor in that whatever aspect ratio is selected the focal length remains the same.

Recently I tried a Panasonic GX80 with the 12 -32mm lens which is 24-64mm in 35mm terms. However at 12mm when set to 16.9 the actual focal length is 26mm, not 24mm

My question therefore is what is the focal length of the 15-54mm lens on say an M3 when the aspect ratio is set to 16.9?
