What is actually happening?

setData doesn't update correctly the data and console print "Cannot read property 'split' of undefined", seems wrapper is not mounted, if i remove data from App.vue SFC error changes and it is "Avoid adding reactive properties to a Vue instance or its root $data at runtime - declare it upfront in the data option."

Thanks for the bug report.

I believe this is an issue with your directive. If you change the data in your component with setTimeout the directive does not update correctly.

Another issue, which is causing the error you are seeing, is that JSDOM doesn't support innerText—jsdom/jsdom#1245
