I have a memory issue when I use WebGrid Inside WebTab. Example, when I open one Tab (there in WebGrid inside it), the memory usage is 20 MB. When I Open another Tab (with the same WebGrid inside it), the memory usage will be increased to 22 MB. That's 2 MB additional. So when I open 10 Tabs in total (9 new tabs) the total memory usage will be 38 MB (20 MB + (2MB x 9 tabs) ). 

Now I'm closing all the tabs. The memory usage still stuck on 38 MB. So when I open 9 new tabs again. The memory usage will be 56 MB (38 MB + (2 MB x 9 tabs ) ). 

Does anyone got any solution on this issue? Thanks before.
