/**
|
||||
* 富文本内容区的几何与聚焦回归。
|
||||
*
|
||||
* 背景：`minHeight` / `maxHeight` 作用在内容区（`.g3-rich-text__content`）上，而
|
||||
* EditorContent 会再套一层包裹 DOM，`.tiptap` 原本写的 `min-height: inherit` 继承的是
|
||||
* 那一层的 computed 值（恒为 0），于是可编辑区只跟内容一样高 —— 空文档时 200px 的内容区
|
||||
* 里只有约 45px 能点，下方全是「点上去既不聚焦也不落光标」的死区。
|
||||
*
|
||||
* 这三个用例分别锁：内容区短时「可编辑区撑满 + 点空白聚焦到末尾」、宿主样式破坏撑高时的
|
||||
* 兜底聚焦、内容长时「可编辑区按内容撑开 + 由内容区滚动（不裁切）」。
|
||||
*
|
||||
* 聚焦、caret 落位与滚动都必须真浏览器：happy-dom 没有真实聚焦、选区与布局。
