Description

Description

When setting IsShowingUser = true, the map center over the user and also set some default zoom level. This creates problems when you want to show the user icon, but on the same time set a custom visible area of the map.

This issue was reported in Bugzilla in 2017 but never solved, from what I can see.

Steps to Reproduce

  1. Put a mapcontrol on a page <Map IsShowingUser="True")/>
  2. Use MoveToRegion() when the page appears
  3. The UWP gets an update of your current location, it will center over you

Expected Behavior

User mark should be shown. No change of visible region should be made

Actual Behavior

The map is centered above the user (and a default zoom level is set)

Research direction
Examine the UWP map control implementation in Xamarin.Forms to understand how IsShowingUser interacts with MoveToRegion. Look for any default zoom or centering behavior triggered by location updates.
