Tab bar should not scroll horizontally after closing a tab

[redtopia]

When closing an active tab with a mouse click, the tab bar will scroll horizontally when the newly active tab is not in view. This behavior can cause a workflow problem when your goal is to close multiple tabs in the same general location in the tab bar, and one of the tabs you want to close is the active editor.

• VSCode Version: 1.34
• OS Version: Win10

Steps to Reproduce:

1. Open a bunch of tabs so that the tab bar is scrollable, and there are multiple tabs to the far right that are not visible
2. Make the first tab (on the left) the active editor
3. Scroll the tab bar to the far right, causing the currently active tab (far left) to be scrolled out of view
4. Make the far right tab the active editor by clicking on the tab
5. Now close the far right tab (which is active)
6. The tab bar will scroll back to the far left to reveal the new currently active tab, which was the previously active editor. You will no longer see the tabs that you intend to close (on the right), forcing you to scroll to the right again.

This problem becomes compounded when you are reorganizing and closing multiple tabs as part of your workflow because changing the location of a tab makes it active, which affects the z-order of the editors.

In my opinion, the tab bar should not change it's horizontal scroll position when closing a tab via a mouse click in the tab bar, even if the next currently active editor's tab is not in view. Or perhaps delay the scroll action until the mouse is moved out of the tab bar.

Does this issue occur when all extensions are disabled?: Yes
