extra Options
Extra style package load options. Accepts the dictionary value with keys of string type. Supported options: - "keep-legacy-style-pack" -> boolean (false by default). Prior to Maps v11 the style packages were stored in the Disk cache, and starting from v11 they are stored in the Tile Store. By default, the implementation removes the style package from the legacy storage after the first successful loadStylePack() call when all the data gets into the Tile Store. Setting this flag prevents from the style package removal from the legacy storage after the loadStylePack() call.
