Input box no longer auto-expands height — stuck at fixed size, cannot select/copy previous input (v1.0.49, Windows)

[kiririto]

Affected version: 1.0.49
OS: Windows, Windows Terminal, PowerShell
Description:
After updating to v1.0.49 on 2026-05-19, the input box at the bottom is now a fixed height and no longer auto-adjusts based on content length. Previously it would grow to fit longer input. This makes it impossible to select and copy previously typed prompts.
Expected: Input box auto-resizes to show full content, as it did in earlier versions.
Actual: Input box is fixed height; longer input scrolls within it but cannot be selected/copied.

Reproduces on Linux too (1.0.49, Linux x64, alacritty host) — not Windows-specific. Same symptom: input box capped at a small fixed height (appears to be ~3 lines). Longer prompts scroll inside the box; the box never grows. Selection/copy of past input is impossible as a result.

1.0.48 on the same system rendered the input as auto-expanding; the regression appeared exactly at the 1.0.49 upgrade. No changelog entry between 1.0.48 and 1.0.49 mentions a change to input sizing.

Looks like a maxLines cap was newly applied to the input component in 1.0.49. Removing that cap (or making it unbounded) restores the 1.0.48 behavior in my testing.
