Discontinued doesn't mean out of use. But I get your point. Maybe it doesn't work on ie7 either. I should just "get with the times" and move to android or iOS. But we're taking about text not rendering correctly on a PWA that otherwise works well. I don't see the harm in reporting it because maybe its one tiny change the author needs to make in order for it to be usable.

Why should anyone support a discontinued browser?
