MapControl has a blue background

[dotMorten]

Describe the bug

The default background of the mapcontrol is blue. This should be the background color of the MapControl.Background property instead.

Steps to reproduce the bug

Launch the mapcontrol. Before it loads the tiles, you'll see the "blue window of death".
Use Two-finger drag to "tilt" the map into 2.5D mode, and zoom out to the entire world. Notice the blue areas above and below

Expected behavior

Background matches the background of my control - at least if it's a solid color brush, you should be able to forward that color to html.

NuGet package version

Additional context

Problem is caused by this line of code:

microsoft-ui-xaml/controls/dev/MapControl/map.html

Line 19 in a7cc340

background-color: blue;

It looks like some early debugging code that was never cleaned up.

Thanks for reporting and investigating this. We've checked in a fix for our first 1.5 servicing release.

@gegao18 What was the change? Is it now wired to the control background?

@gegao18 Hello?

[gegao18]

For 1.5.1 we just took out the blue background. The maps page now has a transparent background, which will show the default white of the WebView2. I'm reopening this to hook up the map background to the control background for the invalid and zoomed out states.

@gegao18 Thanks for the follow up!
