Applying Styles to Dom elements is causing performance issues in iPhone.

hi,

I see an unacceptable lag when I apply style to the sencha controls using jquery in painted event.

Please find the code snippet below.

When I apply the same to Kitchen sink example, I found the same poor performance in iPhone 5 (ios v7).

Code:

{
                        xtype      : 'emailfield',
                        name       : 'email',
                        label      : 'Email',
                        placeHolder: 'me@sencha.com',
                        clearIcon: true,
                        listeners: {
                            'painted': function () {
                                $('#' + this._itemId + ' input').attr('style', 'font: normal 11px Arial !important; color: rgba(235, 17, 17, 1.0) !important; text-decoration:none !important ;text-align:left !important ;height:22px !important; ' + $('#' + this._itemId + ' input').attr('style'));
                            }
                        }
                    },

Adding more controls with styles resulting more lag in type-in and selecting date etc., issues.

Can some one please suggest on this.

Thanks,

Naresh
