[Bug] Can't close tab via middle click if bar is scrollable #15077

Description

Middle-clicking a tab, while the tab bar is scrollable doesn't close it.

This happens because there's no onMouseDown handler calling preventDefault() for middle-click (button === 1), so the default 2D scrolly thing takes over.

OpenCode version

Steps to reproduce

1. Open enough files/etc to make the tab bar scrollable
2. Middle-click a tab to close it
3. Yuck!
