Code To Reproduce Issue

public void scrollUpUntilElementDisplayed(WebElement element) throws NoSuchElementException {
        int windowHeight = driver.manage().window().getSize().height;
        int windowWidth = driver.manage().window().getSize().width;
        do {
            new TouchAction(driver)
                .press(windowWidth / 2, windowHeight / 2)
                .waitAction(Duration.ofMillis(300))
                .moveTo(0, -200)
                .release()
                .perform();
        } while (!element.isDisplayed());
    }
