Behat tests in view_report.feature fail with Firefox

[leonstr]

For example with Moodle 4.3.5+ (Build: 20240705), report_allylti 2024060300 and firefox-115.12.0-1 on CentOS 9:

# vendor/bin/behat --config /var/www/beh_moodledata/behatrun/behat/behat.yml `pwd`/report/allylti/tests/behat/view_report.feature --profile=headlessfirefox
⋮
--- Failed steps:

    	Css matching locator "#settingsnav" not found. (Behat\Mink\Exception\ElementNotFoundException)

This test does pass with Chrome (tested with google-chrome-stable-126.0.6478.126-1).

I think this happens because line 64 of view_report.feature is:

    And I navigate to the course accessibility report

causes Accessibility report to be clicked which causes the report to open. But then the next line:

    And I click on "Accessibility report" "link" in the "#settingsnav" "css_element"

clicks Accessibility report a second time. Maybe in Chrome the report opens in a background tab so Accessibility report is in the active tab to click again, whereas in Firefox the focus moves to the new tab on the first click and so the Accessibility report isn't present to be clicked on again?

Two identical sequential requests when running this test with Chrome can be seen in the web server access log:
