MinkSelenium2Driver recent change breaks webUI tests

[phil-davis]

Steps to reproduce

1. do a composer update to get the latest dependencies
2. you will get later commits of dev-master for https://github.com/minkphp/MinkSelenium2Driver
3. run a webUI test that types in a text box and presses enter, e.g.

bash tests/travis/start_ui_tests.sh --feature tests/acceptance/features/webUIFiles/createFolders.feature:15

Expected behaviour

The test passes.

Actual behaviour

The test fails with:

  Scenario: Create a folder inside another folder                             # /drone/src/tests/acceptance/features/webUIFiles/createFolders.feature:15

Server configuration

Local git repo master branch, or on drone CI.

The problem was introduced by minkphp/MinkSelenium2Driver#286

The setValue method now tries to blur out of the input field after typing the value to be set. But in our case, we already pressed enter at the end of the input, which makes the field go away immediately. So the attempt to blur out fails with StaleElementReference

GitMate.io thinks possibly related issues are #13402 (... broken), #22485 (test), #31579 (test), #22492 (test), and #31408 (Add scenario result to webUI test output).

[phil-davis]

minkphp/MinkSelenium2Driver#292 raises the issue with the upstream project.
