P: Map module doesn't handle HDPI correctly (Win 10)

I have Lightroom 6.2 on a Windows 10 machine with a 4k monitor, set to 150% scaling. Whenever I drag & drop a photo (or group) onto the map module, the item is placed below and to the right of where I dropped it. It _looks_ like the drop location is being scaled by about 150%, relative to the top-left of the map pane. Existing items appear to render in the correct location on the map, and mouse interaction with the map appears to work as expected, so this problem _seems_ to be limited to drag & drop.
