Syncing our private discussions here:

• This is a known bug in Chrome < 74 that spread operator + Proxy doesn't behave correctly https://bugs.chromium.org/p/chromium/issues/detail?id=960744
• There isn't much we can do in Vue.js core to work around this bug
• Object.assign seems to work correctly.
  • So the most straightforward workaround is to transpile spread operators to Object.assign if you target Chrome < 74.
  • With Babel, you can do this by manually adding @babel/plugin-transform-object-rest-spread to your babel.config.js
  • To fix it for all @babel/preset-env users, you can submit a PR to Babel to update the @babel/compat-data package. It currently only transpiles spread operator for Chrome < 60. (Update: it's compiled from https://github.com/mdn/browser-compat-data/blob/main/javascript/operators/spread.json) https://github.com/babel/babel/blob/c3eb254e429ddc52e31fff8fc205010eab65ca40/packages/babel-compat-data/data/plugins.json#L316-L328
• Anyway, it's out of the scope of this repository. So I'm closing this issue.
