Current behavior:

Replication environment: Mac OS X (for PWA)
Different behaviours in Chrome 58.0.3029.96 and Safari Version 10.1 (12603.1.30.0.34) (see videos)

Currently I have replicated the bug on the ionic-preview-app on ionic versions 3.1.1, 3.1.0, 3.2.0

The bug does not happen on 3.0.1.

Description: The key up on the ion-searchbar seems to be broken since 3.1.0 onwards for non latin keyboards. For example I am using a chinese Hanyu pin yin keyboard to type "青山" (qingshan).

However on Safari, the ion-searchbar goes like "qqqiqiqingqinqingqing sqing sqing shqing... ". See video.
On Chrome, the ion-searchbar seems to dismiss the language bar intended to popup.

Expected behavior:

The ion-searchbar should work normally with the different language inputs.

See video.

Steps to reproduce:

1. check out and build the ionic-preview-app and build

2. ionic serve

3. scroll to the ion-searchbar page.

4. change input to chinese and type "qingshan". notice on Chrome the input for chinese does not appear, and on Safari multiple letters appear.

5. Change package.json ionic-angular dependency to 3.0.1

6. remove node_modules and npm install again

7. notice that things work normally.

I've also encountered the same symptom after using 3.1.0. when ion-searchbar had worked correctly with 2.x

I faced the same bug too during inputting Japanese.

I could solve this by replacing from (input) to (change) in https://github.com/driftyco/ionic/blob/master/src/components/searchbar/searchbar.ts#L37 .

I had compared this version3.0.1 and version3.2.1 that I found to modify this function "Searchbar.prototype._inputUpdated" can fixed it
