Reproduction Link

Steps to reproduce

Clone this repro: https://github.com/niboac/vue-element-test, then run: npm install & npm run unit, test this project.

What is Expected?

Expect NO error.

when I remove the directive "v-loading", it has no error. so I think the bug is from v-loading.

What is actually happening?

It shows a error:
/Users/cb/GitHub/vue-element-test-issue/node_modules/vue/dist/vue.runtime.common.js:6903
var transitionDelays = styles[transitionProp 'Delay'].split(', ');
^

TypeError: Cannot read property 'split' of undefined

confirm. have same issue. can be reproduced when doing tests in loop. Occurs time to time.

[adin234]

so, any news?

[industral]

@adin234 I created PR for that vuejs/vue#8281, but looks like nobody interested on it. Please vote for it, so it can be promoted into vuejs

[adin234]

so do we need to use a different fork of vue for the tests to work? :(

[industral]

ideally, wait until they merge it... Unfortunately I can see just tones of PRs in a queue..

[adin234]

so no other choice than to use a fork then. thanks for your work, im using it now @industral :)
