In scenarios where multiple TinyMCE plugins are used, some buttons may be hidden, leading to issues with Behat tests due to unclicked buttons.

To ensure all buttons are clickable, it's necessary to expand all toolbars when multiple TinyMCE plugins are present. Without this step, certain Behat tests, such as mod/quiz/tests/behat/manually_mark_question.feature, might fail because a button was not clicked. The issue can be addressed by adding an additional step to the i_click_on_button step definition, as follows:

$this->expand_all_toolbars($locator);

The final step definition would be:

public function i_click_on_button(string $button, string $locator): void {        $this->require_tiny_tags();

        $container = $this->get_editor_container_for_locator($locator);

        $this->expand_all_toolbars($locator);

        $this->execute('behat_general::i_click_on_in_the', [$button, 'button', $container, 'NodeElement']);

    } 

With this change, the toolbars will always be expanded, ensuring that all buttons are clickable.
