Line height causing visual breakage

Describe the bug

Honestly, I'm not even sure if this is a bug, but I mentioned it on Twitter and was told to file an issue here.

Basically, when using a package such as Laravel Prompts, the output is a bit crunched vertically. When I try to increase the line height, it creates gaps in the output. Somehow iTerm handles this gracefully, not sure how though.

I've tried different fonts, but same result.

To reproduce

Output a box in the terminal and start increasing the line height, you'll see gaps in the lines.

Expected behavior

Gaps shouldn't appear, ideally. The line should be continuous.

Does this block you from using Warp daily?

No

Is this a Warp specific issue? (i.e. does it happen in Terminal, iTerm, Kitty, etc.)

No, this same issue happens in Warp and other terminals.

Reproduce the issue on macOS by rendering a terminal box while increasing line height, using the reported Warp version and comparing the result with iTerm. Since the issue names no files or tests, first locate the terminal rendering and line-height entry points; done means box lines remain continuous without gaps.
