Vue: v-model breaks selectionStart

Hello!

Thanks for filing the issue 😄 . Please follow the Issue Reporting Guidelines and provide a minimal JSFiddle or JSBin containing a set of reproducible steps that can lead to the behaviour you described.

I cloned your repo and tested it on chrome, it works well. Next time provide a simple repro. People can't go through your whole application to help...

Thanks for the feedback. I'll provide a gh-pages link soon. It's impossible to reproduce the bug on the codepen or jsfiddle due to Piano.js nature.

I see, in that case it may be due to Piano.js. It'd be great if you can create a repro without pianojs 👍

@posva Hi again! Here's a codepen with repro
Steps to reproduce:

1. Insert text into first input
2. Select some text
3. Click a button near your input

Looking forward for your response!

Thanks! I found the bug. The update resets those values so caching them here and taking them back there actually solves the issue. I'm not sure about how to test this though. I may have to write an e2e test

PS: I'm doing this tomorrow, going to sleep 😴

I didn't had internet yesterday 😢 I hope being able to do it this evening

Finally got internet back. I'm having some trouble creating a test that breaks as a unit test. I'll try again today with an e2e test although it's a by overkill. Calling the blur method on the input doesn't behave the same way as actually doing.
The fix I came up with is not setting the input value if it hasn't changed at blur. It's basically adding _toString(self._watcher.value) !== el.value to the conditions here
