Overriding a binded prop with hypenated syntax instead of camelCase not working

[AMontagu]

Version

2.5.17

Reproduction link

https://codesandbox.io/s/1zr10x8rpq

Steps to reproduce

• Create two child components with the same prop in camelCase
• Bind props from first child to second
• Try to override camelCase prop in hypenated syntax from first child to second

What is expected?

Prop override correctly

What is actually happening?

Prop keep parent value

---

Meet this issue because I have a camelCase coding stye. But eslint vue-recommended throw an error if prop is not hypenated.

The sandbox seems to be working as expected. What is your expected result?

[AMontagu]

The sandbox show 2 props overrided but only one is really overrided.
My expected result is the two props been overrided and showing : Working.

It's maybe a normal behavior of vue currently but as I said it's a bug if someone code in camelCase and use eslint vue-recommended

Sorry my bad too fast at copy pasting on the sandbox. The sandbox now really show what I mean.
