Something's going wrong with intersection types

[lowasser]

On the Kotlin stdlib documentation, https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.jvm.optionals/java.util.-optional/-any.html shows

fun <T> Optional<out T>.Any()
(source)

which lacks even a shown return type.

Clicking the source leads to the admittedly convoluted line of source

public fun <T> Optional<out T & Any>.getOrDefault(defaultValue: T): T = if (isPresent) get() else defaultValue

It took me a few minutes browsing to figure out what was going on, but the getOrDefault method doesn't actually appear by name anywhere in the generated docs.

Expected behaviour
I would expect the generated Dokka to show the signature

public fun <T> Optional<out T & Any>.getOrDefault(defaultValue: T): T

Dokka supports Definitely non-nullable types since 1.7.0.
This signature would be displayed in Dokka as:

But https://kotlinlang.org/api/ is generated with very old Dokka.
Migration StdLib to the latest Dokka is in progress. See KT-55392

Anyway, this issue is a duplicate of KT-60968 in Kotlin Web Site.
