https://dart-review.googlesource.com/c/sdk/+/126646 introduced the notion of GC working without a current isolate and working solely with isolate groups but all weak persistent callbacks currently work with the notion of having a current isolate being available. The above assertion of having no current isolate breaks the callback code.
