--- Comment #1 from Christophe Strobbe <c_strobbe-fdo at yahoo.co.uk> ---
The bug report does not give a sufficiently convincing rationale for reducing
the number of values that can be chosen from a drop-down list to just one
value.

To make a comparison with HTML, the select element has always allowed
developers to enable the selection of multiple values (by adding the attribute
"multiple"): https://www.w3.org/TR/html52/sec-forms.html#elementdef-select 

Moreover, the ODF 1.3 specification (released in June 2021) does not express a
limitation either. Subchapter "13.5.13 <form:listbox>" of Part 3 says:

The <form:listbox> element defines an input control that allows a user to
select one or more items from a list. It is an alternative representation for a
group of radio buttons.

(Note that the last sentence contradicts the first; if more than value can be
selected, the listbox is an alternative representation of a "group" of check
boxes.)

The more cogent argument would be that selecting more than one value from a
single list box is not user friendly for most users and even more difficult for
keyboard-only users.
See for example the Stack Overflow question "Many people don't know how to
multi-select items in a HTML <select> control, so…?"
https://stackoverflow.com/q/204075/6002174 (The answers can be ignored in the
context of this bug.)

The usability of multiselect drop-downs is sufficiently bad to require
instructions for users near the drop-down list.
