“Non-responders” page: message fields (title/body) not displayed

[yasada0819]

When I open the "Non-respondents" page, the message fields (title/body) are not displayed.

There is an empty area between the "Send message to selected users" text and the "Send" button.
When I click the button, the alert message "[[allfieldsrequired]]" is shown.

Using the Web Developer tools, I found that adding the following CSS makes the form visible (and it works as expected):

#page-mod-questionnaire-show_nonrespondents .table-responsive {
overflow-x: visible !important;
}

This seems to be caused by the table-responsive container hiding the message form.

Environment:

• Moodle 5.1.1 / Moodle 5.0.4
• Plugin version 5.0.1 (Build 2025110900)
• Theme: Boost / Boost Union v5.1-r1 / Boost Union v5.1-r3
