bug: Button style messed up in header when modified

[ErkoKnoll]

Type: bug

Ionic Version: 2.x

Platform: android 5.1 webview

When button is placed in the header and when angular triggers view update it's style will become of the button like its not placed in the header.

Example code:
<ion-navbar *navbar> <ion-title></ion-title> <ion-buttons end> <button *ngIf="..."> <ion-icon name="compass" style="font-size: 30px;"></ion-icon> </button>

Screenshot where compass icon has ngIf directive and it gets updated after creation.
