DT is broken in Safari

paulirish opened this issue · comments

TypeError: Illegal constructor

image

cuz no support for constructable stylesheets: new CSSStyleSheet()

Safari Tech Preview seemingly has support...


However Safari TP then breaks on typeerror: i.setIconType is not a function . I think thats cuz its a subclass of a native HTMLElement and perhaps Safari TP doesn't support that:

In today's safari i don't see either of those errors but i see TypeError: undefined is not an object (evaluating 's.checkboxElement.checked=Boolean(t)')
