Programmatic linking of labels with form elements takes place with "label" elements via the "for" attribute or the inclusion of the labeled form element in the form element in the "label" element. If labels are not marked with the "label" element element, a label for the associated form element should be created in another way other way (e.g. via the "aria-labelledby" attribute).

Personal: Partially fulfilled.

• [ ] When focusing the slider "Tile size" in the menu "Customization options for the Show file list customization options" menu, the accessible name is not displayed because the programmatic linking using the "for"/"id" attributes does not work. The corresponding "id" attribute is missing in the "input" element.

Spaces: Partially fulfilled.

• [ ] The "Filter members" field in the "Members" section is not accessible as it is not programmatically is not programmatically linked to a label. Although a "label" element is present, it does not contain any text. A placeholder is not a suitable replacement for a label, as it is not output in many cases.
