Research direction
Start with the linked StackBlitz reproduction and compare MatchData#end results from eval and evalAsync for the Unicode match. Trace the async path responsible for the offsets; done means evalAsync returns the same offsets as the synchronous calls: 3 for end(0) and 1 for end(1).

Description
Stackblitz reproduction: https://stackblitz.com/edit/ruby-wasm-demo-78s71k?file=index.html
MatchData#end returns incorrect match offset when used in async context:
vm.eval(/(т)(е)(с)/.match('тест').end(0)) #=> 3
vm.eval(/(т)(е)(с)/.match('тест').end(1)) #=> 1
vm.evalAsync(/(т)(е)(с)/.match('тест').end(0)) #=> 3291
vm.evalAsync(/(т)(е)(с)/.match('тест').end(1)) #=> 3
