Backdrop Enabled Blocks Mouse Input on Underlying Google Map Widget (Web Only)

[max-anders]

Describe the bug
When backdropEnabled is set to true on a SlidingUpPanel positioned above a GoogleMap widget, it blocks mouse interactions on the map, preventing users from dragging or interacting with it on Web.

To Reproduce

1. Add a GoogleMap widget.

2. Place a SlidingUpPanel widget above it. (using Stack)

3. Set backdropEnabled: true on the panel.

4. Attempt to drag or interact with the map in a web environment.

5. Expected Behavior:
   Users should be able to interact with the Google Map widget behind the panel when backdrop is enabled, or have an option to disable the backdrop interaction block on Web.

6. Environment:

   • Platform: Web
   • Package version: Flutter 3.24.3
   • Browser and version: chrome v130

Note:
I spent quite a bit of time trying to figure this out, so I hope this helps others who might be dealing with the same issue!
