Consider the following scenario:
You use an application that creates WebBrowser controls.
The application uses a SessionStorage object to store sessions in Internet Explorer 11.
In this scenario, you encounter the following issues:
When the application creates a control in a separate thread (such as create a new tab), the data of the SessionStorage object is shared incorrectly.
Note This issue also occurs when the application creates a control on a same thread. See article KB3012780 for more information.
When the application creates controls repeatedly, the performance of Internet Explorer becomes slow.
To resolve this issue, install the most recent cumulative security update for Internet Explorer. To do this, go to Microsoft Update.
