I realized we don't have a test yet for adding a waitable to a set while it's involved in a sync operation; will add one. |
...and vice-versa. Per WebAssembly/component-model#647, a waitable may not be added to a waitable-set while it's being used in a synchronous operation, nor may a waitable that's already added to a waitable-set be used in a synchronous operation. Test case courtesy of Alex via bytecodealliance#13212. Fixes bytecodealliance#13212
