在 UI 测试 (XCUITestCase) 中，当我尝试让测试点击 anMDCMultilineTextField时，测试失败并显示

元素和任何后代都没有键盘焦点。

如果我尝试使用 UI 测试记录器并点击MDCMultilineTextField它无法找到带有错误的多行文本字段：

时间戳事件匹配错误：未能找到匹配元素

我的测试用例

let descField = app.otherElements["EventEditor-TextField-Desc"]
let exp = expectation(for: NSPredicate(format: "exists == true"), evaluatedWith: descField, handler: nil)
XCTWaiter().wait(for: [exp], timeout: timeout)
descField.tap()
descField.typeText("Desc 4")
let saveButton = app.buttons["EventEditor-Button-Submit"]
saveButton.tap()

，其中EventEditor-TextField-Desc是分配给 的可访问性标识符MDCMultilineTextField。

运行测试时，它无法告知Neither element nor any descendant has keyboard focus.并将该行标记descField.typeText("Desc 4")为有错误。详细错误描述：
