fillField() ignores performOn()

[mbrodala]

Given the following basic form structure:

<label for="title-1">Title</label>
<input id="title-1">

<div class="nested">
    <label for="title-2">Title</label>
    <input id="title-2">
</div>

The following snippet will always fill the first Title field instead of the second one:

$I->performOn(
    ['class' => 'nested'],
    ActionSequence::build()->fillField('Title', 'Test')
);

The reason for this is that WebDriver::fillField() uses the internal WebDriver::findFields() method and that one always uses $this->webDriver (the RemoteWebDriver instance) as base instead of WebDriver::getBaseElement().
