Navigation Map Macro Size Configuration is Not Working

Confluence Navigation Map Macro documentation describe that it need px string to configure the size of the macro when it rendered.

However, changing the size of the macro with px at the end of each value (width and height) doesn't change the size of the macro. But, removing the px at the end of the value successfully change the size of the macro.

I believe this is a bug because the default value when the macro created use px at the end of the value as describe in its documentation.
