I have not install this packages ("composer show"). So there is no need for me to install them.

@bugToaster: I have no "codeception/module-filesystem" or "symfony/browser-kit" line in my composer.json.

My suggestion to add "symfony/css-selector":"~2.8|~3.0|~4.4", "symfony/dom-crawler": "~2.8|~3.0|~4.4" (what Discomania have done in the fix) doesn't resolve the issue. A downgrade to 3.4.47 of symfony/dom-crawler and symfony/css-selector will be done, if I remove my workaround ("symfony/css-selector": "4.4.37 as 3.0.0", "symfony/dom-crawler": "4.4.39 as 3.0.0") in my composer.json and then an exception will thrown if using the control. Sorry I have no other suggestion. I use my workaround again.
