Issue Description

When selecting text and then pulling the cursor out of the window on the level of the title bar of the ghostty window (to make the window scroll up wihle selecting text). After lowering the cursor again to a level below the title bar the window starts to scroll down somehow. This does not happen while the cursor stays inside the ghostty window itself. This happens with the newest 1.2 release on mac os.

Scroll.mp4

Expected Behavior

The window should not scroll down, it should be the same behaviour as if the cursor was inside the window.

Actual Behavior

Window starts to scroll down once the height of the cursor outside the window is below title bar again.

Reproduction Steps

1. Open a ghostty window
2. Produce enough text to scroll
3. Select text and drag the cursor outside of the window over the height of the titlebar
4. lower the cursor outside of the window below the titlebar again (while still selecting text).
5. => Window starts to scroll down

This happens on Linux too.
