drag_to clicks links #2580

Meta

Capybara Version:
3.37.1
Driver Information (and browser if relevant):
Selenium 4.2.1 on Chrome 105

Expected Behavior

Calling drag_to on a link causes Capybara to first drag/drop it and then click it. I don't understand why it would click it but that's what happens. It shouldn't.

Actual Behavior

The link is clicked.

Steps to reproduce

require 'capybara/dsl'
require 'selenium/webdriver'

html = DATA.read
app = proc { [200, { 'Content-Type' => 'text/html' }, [html]] }

sess = Capybara::Session.new(:selenium_chrome, app)
sess.visit('/')
sess.find_link.drag_to(sess.find('div'))
puts sess.has_css?('div', exact_text: 'qwe')

__END__
<html>
  <body>
    <a href="https://google.com" draggable>foo</a>
    <div>qwe</div>
  </body>
</html>

Run this. The drag_to line causes a transition to google.com. Then has_css? fails (as it's on a different page).

Not much that can be done about this. Capybara doesn't send a click event, it sends the HTML5 drag events (since an A element is by default draggable) -- then either the driver or the browser is interpreting the release of the mouse after dragging as a click

I don't think it's the browser because 1) doing such a drag and drop manually doesn't cause a transition and 2) I used to use my own implementation of such a functionality which works fine. Perhaps the problem is in click_and_hold and then release? I would be surprised for that to be a bug in Selenium though - no one to have hit such a problem.

I've seen this in the past specifically on CI. The issue seems to be that if the drag_to element is not an actual drop handler, the browser ends up sending a click instead of a drag. It seems to be that the mouse doesn't actually move/drag to that point.

Guys, any update on this one? We're a bit stuck with this on not being able to update to 3.40 (which fixes empty attachments thing).
