What are you trying to achieve? (Expected behavior)

I am using php-webdriver for unit-testing, in which one test involves dragging and dropping a specific element. In 1.7.1, this was written as

        $actions = new WebDriverActions($this->driver);
        $actions->dragAndDropBy(
            $this->element,
            0,
            -50
        )->perform();

and it worked perfectly.

What do you get instead? (Actual behavior)

After the auto-update of composer to 1.8.0, the test threw a MoveTargetOutOfBoundsException.

Some debugging attempts did not solve the problem. In 1.7.1, the HttpCommandExecutor::execute got the following inputs:

$raw => {"method":"POST","url":"\/session\/:sessionId\/moveto"}
$http_method => "POST",
$url => "\/session\/3fcbbbc0446b4c1bbb7cae8e0424c3a5\/moveto",
$params => {"xoffset":0,"yoffset":50},

In 1.8.0 there seemed to be at least 2 relevant executed commands:
1:

$http_options => {"url":"\/session\/:sessionId\/actions","method":"POST"},
$http_mehtod => "POST"
$url => "\/session\/c38e68185246f7f29fe206c62d2a6c19\/actions"
$params => {"actions":[{"type":"pointer","id":"mouse","parameters":{"pointerType":"mouse"},"actions":[{"type":"pointerMove","duration":0,"x":0,"y":0,"origin":{"element-6066-11e4-a52e-4f735466cecf":"b72b8ae5-b44c-44be-8b27-d7fca391e562"}},{"type":"pointerDown","duration":0,"button":0}]}]}

2:

$http_options => {"url":"\/session\/:sessionId\/actions","method":"POST"}
$http_method => "POST"
$url => "\/session\/c38e68185246f7f29fe206c62d2a6c19\/actions"
$params => {"actions":[{"type":"pointer","id":"mouse","parameters":{"pointerType":"mouse"},"actions":[{"type":"pointerMove","duration":0,"x":0,"y":-50}]}]}]

The second execute gives the error. Maybe the problem is solved when this is also given an origin? I'm not sure.

How could the issue be reproduced? (Steps to reproduce)

The Selenium server is initialised by exec vendor/bin/selenium-server-standalone within a proc_open, and the webdriver by RemoteWebDriver::create(localhost:4444/wd/hub, $caps)

The relevant HTML is

<div class="list-group overige_stukjes" id="overig">
    <a class="list-group-item stukje" href="/mails/bewerk/3/7" data-id="7" data-categorie="overig" data-volgorde="1">
    <em>Naamloos stukje</em>
    </a>
    <a class="list-group-item stukje" href="/mails/bewerk/3/8" data-id="8" data-categorie="overig" data-volgorde="2" style="">
    <em>Naamloos stukje</em>
    </a>
</div>

Here I try to move the Naamloos stukjes up or down. Maybe the following JavaScript is also relevant (Using JQuery):

 // Drag/drop van mailstukjes
        $('#overig').sortable({
            nested: false,
            group: 'overige_stukjes',
            containerSelector: '.overige_stukjes',
            itemSelector: 'a.stukje',
            placeholder: '<a class="list-group-item huidig-stukje"> </a>',
            onDrop: ondrop,
        });

Again, the php trying to do the drop-and-drag looks like this:

        $actions = new WebDriverActions($this->driver);
        $actions->dragAndDropBy(
            $this->element,
            0,
            -50
        )->perform();
