IE9 persistance issues on v0.3.9

[kubosador]

Hi,

There are some troubles with IE9 and sessionStorage.
I know this is an old browser but we still have to maintain it due to legal matters.

I have not dug what's wrong, but there are no synchronisation between $sessionStorage and the current scope on version 0.3.9. When I falled back to 0.3.3, synchronisation worked again.

There might be a regression between those versions.

Hi @kubosador! I reported this issue already here #167. That is better explained here #47.
It seems that this solution #167 (comment) makes the storage work again in IE9.
Around line 193 of ngStorage.js you can replace
if (storageKeyPrefix === event.key.slice(0, prefixLength)) {
with
if ((!$window.document.hasFocus || !$window.document.hasFocus()) && storageKeyPrefix === event.key.slice(0, prefixLength)) {

Thanks for your quick answer. I'll test this solution in my next delivery.

I'll get it in soon. But it seems some tests fail with this fix.
