Not catching activities on JB/4.1

[tvierling]

After altering xposedminversion as described in #2, Xposed now lets me install and enable the mod without any errors. However, it doesn't seem to be catching the embedded Chrome activities on JB/4.1. For instance, in the older Google News & Weather app, adb shell dumpsys activity activities shows this when clicking on a random news article, which opens in the embedded browser. I note that the package and activity name are exactly what this mod intends to catch (com.android.chrome/org.chromium.chrome.browser.customtabs.CustomTabActivity):
