Hot reload doesn't reflect changes in <script>

[tomexx]

Reporting a bug?

After migration to Vue3 the project stopped to properly hot-reload changes in <script> part of the SFCs. When stripped out the project to the bare minimum I realized it is cused by vue-i18n package (I'm using 9.2.0-beta.1). If I remove the vue-i18n the app hot-reloads properly.

Expected behavior

Hot-reloading working correctly (reflecting also changes in <script> part of the SFC)

@tomexx
Seems issue is duplicate to #568, it is caused by vue-next.
See also vue-next issue #4174.
You can fix this by upgrade vue-next version to 3.2.0-beta.5 or later.
Hope this helps.
