[🐛 Bug]: webElement.sendKeys carriage return to a textarea

See original GitHub issue

What happened?

I am using selenium to type multi-line text to <textarea> in html. When the text contains carriage return character (\r or U+000D), I found selenium didn’t type it in the text area (attached my reproduction code). The newline character (\n or U+000A) is typed.

According to <textarea> w3c standard, <textarea> normalizes newline remaining \r. https://html.spec.whatwg.org/#the-textarea-element:normalize-newlines https://infra.spec.whatwg.org/#normalize-newlines quote “To normalize newlines in a [string], replace every U+000D CR U+000A LF [code point] pair with a single U+000A LF [code point] and then replace every remaining U+000D CR [code point].”

When I use selenium to sendKeys a text with both \r\n and \r (e.g. “line 1\r\nline 2\rline 3”), I only see \n was typed but \r is ignored. Because if \r is also type, I would see <textarea> normalize \r\n -> \n and \r -> \n.

Without using selenium, I can prove the \r can be typed to <textarea> and is normalized to \n. This is my jsbin demo code: https://jsbin.com/xapisezini/edit?html,js,console,output

How can we reproduce the issue?

/* reproduce selenium sendKey test */
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import java.util.concurrent.TimeUnit;
public class MyTest {
    private WebDriver driver;
    @Before
    public void setup() {
        System.setProperty("webdriver.chrome.driver","chromedriver");
        driver = new ChromeDriver();
        driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
    }

    @Test
    public void testTextArea() throws InterruptedException {
        driver.get(<localhost URL to hello.html>);
        WebElement ta = driver.findElement(By.id("w3review"));
        ta.sendKeys("line 1\r\nline 2\rline 3");
    }

    @After
    public void teardown() {
        driver.quit();
    }
}

/* hello.html */
<!DOCTYPE html>
<html>
<body>
<h1>The textarea element</h1>
  <p><label>Reproduce sendKeys:</label></p>
  <textarea id="w3review"></textarea>
</body>
</html>

Relevant log output

After selenium sendKeys to <textarea>, the observed textarea is
line 1
line 2line 3

I am expecting desired textarea
line 1
line 2
line 3

The best way to get one of the browser vendors to look at something is to write a web platform test and show that it is passing in one browser and not another… Not sure where it fits in here, but if you can PR something here it should get looked at: https://github.com/web-platform-tests/wpt/tree/master/webdriver/tests/element_send_keys

If you get it figured out, tag me in the PR or link to it here so I see it.
