The scroll bars within some menus don't reset their positions to the top of the lists when resizing the game window

The Bug:

The scroll bars within some menus don't reset their positions to the top of the lists when resizing the game window.

When scrolling to the bottom of the multiplayer tab in offscreen and then going back to fullscreen the scroll bar is in the position that it should be, but the view goes over the bottom of the screen. (See images below, they speak a lot)

Affected Menus:

Please note that this issue may affect more menus that aren't listed below.

• Multiplayer menu server list
• Resource pack menu list

Steps to Reproduce:

1. Have multiple servers within the multiplayer menu in order to make the scroll bar appear.
2. Scroll down to the bottom of the list.
3. Resize your game window and look at the positioning of the scroll bar.
4. Take note of how the scroll bar within some menus doesn't reset its position to the top of the list when resizing the game window.

Observed Behavior:

The scroll bars don't reset their positions to the top of the lists. This occasionally causes them to appear outside of their boundaries.

Expected Behavior:

The scroll bars would reset their positions to the top of the list.
