title: can't find text box element by xpath or css selector
body: <p>I am trying to enter some text into a text box on a webpage, here is the screenshot <a href="https://i.stack.imgur.com/Isgu4.png" rel="nofollow noreferrer">screenshot for Enter Symbol</a>.</p>
  
  <p>My code works fine for all other elements except for the highlighted text box in the screenshot:</p>
  
  <pre><code>WebDriverWait(driver, 40).until(EC.visibility_of_element_located((By.XPATH, '//*[@id="main-content-column"]/div/div[3]/div/div[1]/form/div/div/div[2]/input'))).send_keys("aapl")
  </code></pre>
  
  <p>It doesn't look like in a frame or iframe. Please see the source code for the website:</p>
  
  <pre><code>&lt;input type="text" autocomplete="off" autocorrect="off" autocapitalize="off" placeholder="Add a symbol..." class="sec-search-box bc-form__add-symbol-input ng-pristine ng-invalid ng-invalid-required ng-touched placeholder" data-ng-model="userEnteredSymbols" data-barchart-clear-input="" required=""&gt;
  </code></pre>
  
  <p>Thanks a lot.</p>
