Behat consistent error with chrome/chromedriver 86

While running the Moodle 3.10 testing release matrix we have been using Chrome (and chromedriver) 86, to see if everything is ok with them and can be declared as a valid browser combination.

Using it, there is a consistent error that is passing perfectly with older Chrome versions, both with windows and mac (at the time of creating this, it has not been tested with linux).

This is the error:

002 Scenario: Manager can delete both course and public templates       # /Users/stronk7/git_moodle/testing/mod/feedback/tests/behat/templates.feature:163

      And I should see "Are you sure you want to delete this template?" # /Users/stronk7/git_moodle/testing/mod/feedback/tests/behat/templates.feature:179

        "Are you sure you want to delete this template?" text was found but was not visible (Behat\Mink\Exception\ExpectationException)

(note that the other 4 errors in that run, SCORM ones, have been commented at MDL-61690)

Before being able to bump the CI infrastructure to Chrome 86 (or later) we need this issue fixed.

Ciao
