Tab closing bug

[TriarIma]

Instead of closing tab and erasing its contents, close tab button moves tab conents 1 tab to the right, making the last tab content disappear.

To reproduce this bug, you need to follow the steps below:

1. Create 4 tabs (4 is used as an example, any amount of tabs more than 1 will be enough);
2. Change the pages the tabs contain using Right click and "Inspect element", so you could tell which page belongs to which tab;
3. Close the 2nd tab;
4. Now the contents from the 2nd tab will move to the 3rd tab, 3rd tab's contents will move to the 4th tab and 4th tab's contents will disappear;
5. All of the tabs that go before the closed tab will remain unchanged.

It's pretty obvious that this is not how it should work. Normally it should remove the tab and erase its contents, without affecting other tabs.
