If the document.domain property is set in the page, _has module throws error "Access is denied" when try to check window's property for example 'hasOwnProperty'.

  try {
    return hasOwnProperty.call(it, key);
  } catch(e){
    return

Autoprefixer and Browserslist moved to caniuse-lite. So let’s use it here too. It is very easy, API is the sam

Viewing the test page on Firefox has all tests pass except the one that checks the left position. The tests will all pass in responsive design mode, but not in normal viewing mode.

To reproduce:

• Open the test page in Firefox, not in responsive design view

It's recommended to use this library in the form of a ponyfill, which doesn't inflict modifications of the global object.

The index.js file of the project does the ponyfill work already. Telling us to use the library in the form of a ponyfill is misleading, it should say something like "Th
