Could the automatic scrollToBttom() behaviour made to be configurable/togglable?

[vidosits]

In terminal.ts a scrollToBottom() call is made after each write().

ghostty-web/lib/terminal.ts

Lines 573 to 576 in 03ead6e

	// Phase 2: Auto-scroll to bottom on new output (xterm.js behavior)
	if (this.viewportY !== 0) {
	this.scrollToBottom();
	}

Even if the user scrolls up, the terminal just scrolls back to the bottom on the next write. Imagine that there's a log being streamed through a websocket and the user temporarily wants to scroll back for something that was written to the terminal earlier. They have a small window to do that, before the next line gets written and it scrolls to the bottom again.

xterm.js had this same issue and was eventually handled.
