Missing stdlib functions in API ref

I can’t find API docs on the website for extensions such as LongArray.copyInto. Is a refresh needed, is there a bug, or am I just looking in the wrong place?

Here it is: copyInto - Kotlin Programming Language

It’s the first link that appears when you type copyInto into the search box.

Thanks! Sorry I missed it, I should have looked at the package name of _Arrays.kt.
