[Walker-ZHAO]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

Load custom scheme url by set windon.location .

On iOS/Android/macOS, shouldOverrideUrlLoading callback can be called.
On Windows, shouldOverrideUrlLoading callback can not be called. Get the error in onReceivedError callback, the error content is: error: {description: Indicates that the connection was stopped., type: 9}

Expected Behavior

On Windows, when load custom scheme url by set window.location, shouldOverrideUrlLoading callback can be called as other platforms.
