fix(mobile): don't clear textarea during compositionstart

Browse Source 
Programmatic _textarea.value = '' during compositionstart cancels the
active IME composition on iOS Safari, breaking Chinese character input.
The phantom (U+200B) is invisible and _strip() already removes it
before sending to PTY — no need to clear it manually.
