Navigation Deeplink with "mapcolumn"

Does anyone have expierience with the “mapcolumn” link parameter?
It is mentioned here under “Manually Constructing Deep Links”.

Under UX > Views I have defined my map column [XY] for my “Map_View”.
I want to use the LINKTOFILTEREDVIEW() to open the map with a different map column: [XY_VC]

Something like:
LINKTOFILTEREDVIEW("Map_View", <<Filter_Condition>>) & "&mapcolumn=XY_VC"

I’m pretty sure that this was working until yesterday. But now, the mapcolumn parameter will be ignored.

I know I could solve this by creating another map view. But I thought I could avoid this.
