bug: Keyboard Accessory Bar

[ionixjunior]

Type: bug

Platform: ios 8 webview

When **cordova.plugins.Keyboard.hideKeyboardAccessoryBar(false);** configuration is disabled, the nav buttons of the keyboard are shown when a input focused.

The problem: only on first time, when you change the input by nav button of the keyboard accessory without typing anything on this field, the nav button puts the focus on the same field. On the second click on nav button of the keyboard accessory the operation works perfectly.

I tested it with a Ionic Blank project. This behavior can be visualized on Ionic View with App ID 3240667d

Tested on simulator and device.
