using typescript targeting ES2022 (or newer likely) silently breaks @observable and @bindable (partially)

I'm submitting a bug report changing typescript from targeting ES2022 from ES2021 will silently break aurelia in some non-obvious ways. Any getters/setters done through prototyping are broken. Any getters/setters done afterworks succeed.

Simple view of the generated js and why its an issue: https://page.thepages.workers.dev/aurelia_cry

Simple repo from the default blank project: https://github.com/mitchcapper/aureliaV1_es2022_target_repo and the single commit that differs from the empty project: 2e2b9c7d027574554a59a56834a8ee7c5b486ca1

change it from es2022 to es2021 and it is fixed. Note you must restart the webpack engine after the change it will not auto-pickup that.

Current behavior: When targetting ES2022 things like observable decorators are broken

Expected/desired behavior: Same as with ES2021 where they work without issue

I don't know if this effects V2. I changed the targeting when trying to get an old aurelia project to work with more modern/node/webpack so tried to version up everything. As many things seem to work when this bug is present it took a good while to do the RCA.
