Fix possible exception in old Firefox versions #369

Closed dudabone closed 2 years ago

dudabone commented 5 years ago

In older versions of Firefox, window.getComputedStyle may return null when element is invisible (see https://bugzilla.mozilla.org/show_bug.cgi?id=548397). This causes an exception in the polyfill
