Steps to reproduce

1. I created a custom module in my project to enable Poll.
2. Created a test file by extending BrowserTestBase.
3. In my test function,
-> I have logged in to the site and navigated to 'poll/add' page.
-> I filled the first choice by $this->getSession()->getPage()->fillField('choice[0][choice]', 'Test choice 1');
-> Then I clicked on Add another item by $this->click('#edit-choice-add-more');, I tried with $this->submitForm([], 'Add another item');- as well by referring to the module test file /poll/tests/src/Functional/PollTestBase.php
