Navigation in off-canvas ipad error

Hi everybody,

i'm using the latest version of t3 (blank bootstrap 3) template. All works fine, but the navigation makes some problems.
Using off-canvas with default joomla navigation for small devices works like a charm but not for ipad (ipad mini).

The problem is:

after clicking on menu icon to open the off-canvas sidebar it automatically redirects to the active menu item.

Example:

Menu Navigation inside the off-canvas sidebar:

News
Some external link www.google.de

If i open the off-canvas sidebar it will automatically redirect to www.google.de....

Any android device has no problem with this.

Please help.
