In IE 11 the first input event on a text input is blocked if placeholder is set and the model is initialised

[spectrum128]

Version

2.5.22

Reproduction link

https://jsbin.com/dobagokure/1/edit?html,js,output

Steps to reproduce

1. Open https://jsbin.com/dobagokure/1/edit?html,js,output in IE 11.

2. Enter a single character in the text input just after 'Hello Vue!'

3. Model will not be updated on the first character input but will be on subsequent inputs

*Note to reproduce a second time you will need to refresh the page.

What is expected?

When a single character is entered the model should update

What is actually happening?

The input event is blocked and the model does not update until a second character is entered.

I believe it could be related to a previous fix for an issue that IE11 is firing an input event when the placeholder is set:

Perhaps it should check if the value is set first before blocking the initial event?
