Contributed "Navigate Back" mapping conflicts with default "Zoom out" mapping

[el2iot2]

The binding contributed for workbench.action.navigateBack conflicts with the default binding for the editor "Zoom Out" command. This was masked by vscode 37034 so that the Source of the new binding was "Default" instead of something more clear (like "vs-keybindings" as proposed here or here ). This led to me submitting an issue (now closed) here, but then ending up with this report.
