我有这段代码：
const elem = element(by.xpath(selector));
browser.getCurrentUrl();
browser.wait(() => elem.clear().getText().then(text => text === ''), timeout, `Waiting for element '${selector}' to be cleared timed out`);
工作正常。但是如果我删除了browser.getCurrentUrl（），它就会失败。
const elem = element(by.xpath(selector));
browser.wait(() => elem.clear().getText().then(text => text === ''), timeout, `Waiting for element '${selector}' to be cleared timed out`);
以下是错误的一部分：
- Failed: invalid element state: Element is not currently interactable and may not be manipulated

为什么我会这样做？
正确的方法是什么？如果我不需要，我不想要求当前的URL。我也想了解这个问题。
谢谢
