This is the vue-jsx boilerplate with an additional input element added.

The following babel error shows up in the console:

Error: This API has been removed. If you're looking for this functionality in Babel 7, you should import the '@babel/helper-module-imports' module and use the functions exposed  from that module, such as 'addNamed' or 'addDefault'.

The repro does not use event modifiers but maybe that feature needs to be disabled?
https://github.com/vuejs/babel-preset-vue#jsx-features says they are not supported
