/**
* Cancelable promise.
*
* This file contains an integration of p-cancelable library.
* For usage examples please @see https://github.com/sindresorhus/p-cancelable/tree/v2.0.0#readme
*
* How to update:
* 1. Take resources of p-cancelable package from npm. E.g. using unpkg: https://unpkg.com/browse/p-cancelable@2.0.0/index.js (normally it's just a single file — `index.js`);
* 2. Transpile the file to make it compatible with IE11. To do so, Babel.js REPL can be used:
* 2.1. Open https://babeljs.io/repl/#?browsers=ie%2011
* 2.2. Unselect all presets except ENV preset.
* 2.3. Set browser to "ie 11" if it's not set
* 2.4. Paste index.js from the package to get a transpiled version.
* 3. Update this file. Please pay attention to the modified parts by SAP.
