fix(sender): keep inline custom inputs editable - #2032
advance-hub wants to merge 3 commits into
Conversation
Why: controlled Sender updates recreate inline components.input functions. React then replaces the custom input node, dropping focus after the first character. The existing ref handling also only recognized antd TextArea and left custom Input nativeElement and insert unavailable. What: resolve native input and textarea elements from both antd ref shapes, preserve selection across controlled node replacement, and make imperative focus, blur, nativeElement, and insert work for custom Input components. Add a regression test with the reported inline controlled pattern. Testing: 25 Sender tests; package TypeScript check; Biome; git diff --check; real Chrome continuous abc input with focus retained.

Custom inputs that forward their ref directly to a native element still lose the new focus, selection, and insertion behavior. Resolve that compatibility gap before merging unless it is explicitly accepted.

一只兔子轻敲键盘，输入字符安稳落下。
焦点留在原处，选区也回到旧位置。input 与 textarea 都能接住文本。insert 将新字放入光标旁。
小爪收起，测试确认值仍在。

支持直接返回原生元素的 ref。
当自定义组件将 ref 直接挂到 <input> 或 <textarea> 时，inputRef.current 就是该 DOM 元素。当前函数只读取 .resizableTextArea、.input 和 .nativeElement，因此会返回 null。
这会使该自定义输入无法恢复焦点和选区，insert() 也会提前返回。请先识别 inputRef.current 本身是否为 HTMLInputElement 或 HTMLTextAreaElement，再处理 antd 的 ref 结构。增加直接渲染原生 <input ref={ref}> 的回归测试。

I found one focus-ownership regression on exact head 9ff619c9b54c4d76088aaf07a6b0aedf8d7e98b8.
mergeOnChange now records restoreSelectionRef for every change, and the following layout effect unconditionally calls inputElement.focus(). This also runs when the input node was not replaced. If a controlled consumer intentionally moves focus inside its onChange callback—for example, setValue(next); submitButtonRef.current?.focus()—the committed render runs this layout effect afterward and steals focus back to Sender. That changes existing focus behavior and can disrupt keyboard flows.
Please gate restoration on the focus having been displaced by the inline custom-input replacement, rather than merely on a pending selection. One robust boundary is to record whether the changed input was active and its node identity, then restore only when that formerly active node was replaced and focus did not intentionally move to another connected focusable element. Please add a regression where onChange deliberately focuses a sibling button and verify the button keeps focus, while retaining the current inline-component replacement case.
I also confirmed the worktree is clean after the review probe. My local full Sender run is not usable evidence because this reused worktree currently resolves duplicate/mismatched React copies; the finding follows directly from the effect ordering and unconditional focus() path above.

Fixes #1944
💡 Background and Solution
Why
A controlled Sender re-renders its parent after every
onChange. Whencomponents.inputis declared inline, that render creates a new component function, so React replaces the underlying input node and focus is lost after the first character.The previous imperative ref implementation also assumed an antd TextArea ref (
resizableTextArea.textArea). A custom antd Input usesref.input, leavinginputElementandinsert()unavailable.What
focus,blur,inputElement, andinsert()for custom single-line Input componentscomponents.inputpatternHow
The change records the input selection before forwarding
onChange. A layout effect restores focus and selection to the newly mounted native control. The pending selection survives Sender's internal update and the parent controlled update, then clears after the render cycle.Native input resolution is shared by the imperative methods, so custom Input and the default TextArea follow the same code path.
🔎 Browser verification
Before the fix, entering

🎬 Before / After browser recording
The same controlled inline custom Input was used to type abc at the same speed and viewport. Each GIF preview links to the original MP4.
Before — input stops at a and focus moves to BODY
Open the original before MP4
After — value reaches abc and focus remains on INPUT
