I'm having trouble parsing the linked bugs and if this is fixed or the fix was to disable requestIdleCallback, any chance this can be re-landed anytime soon?

Hi, curious what the latest status on this issue is? Is there any appetite for investigating the regression and adding support?

Hi, Webkit seems the last piece of the puzzle for all major browsers support. I was working on adding Prefetch work during Idle Browser periods in Compose Multiplatform Web framework by Jetbrains. See https://github.com/JetBrains/compose-multiplatform-core/pull/2928
