Apple typically makes good decisions, but they don't always do that or act in your best interest. And that's the problem with supporting all their decisions without checking if they're good or not for you.

In this case, iOS isn't capable of handling different rending engines well. So instead of asking them to improve iOS so this isn't a problem (like it isn't on Android and even other iOS apps), you side with their decision of breaking/removing a feature, even though it doesn't benefit you in any way.

I'm sure you can see the problem with this.
