Android Studio's scratch files are not fully supported in Kotlin 2.0

How can I bypass Android Studio's restriction on scripting in Kotlin 2.0 when using scratch files? Android Studio Ladybug 2024.2.1 displays the following message at the top of the Code Editor:

//    K2 mode: Kotlin scripting is not fully supported.

That warning isn't bogus; there's two options available:

• wait for this issue to be closed: KT-58635 K2: Support Kotlin Scripting.
• use Kotlin version 1.9.25 instead.
