Browse Data Copy function doesn't actually copy Date/Time to Clipboard

Details for the issue

What did you do?

Open Browse Data on table with field of DATE type that contains valid date information.
Hit Control-A to highlight all records
Right-click and choose Copy or Copy with Headers

What did you expect to see?

When pasted anywhere, I expected to see the Date information from each record

What did you see instead?

Nothing, it inserted tabs to separate the field, but no actual field data.

Useful extra information

DB4S v3.13.1 [built for x86_64-little_endian-llp64] on Windows 10 Version 2009 (winnt/10.0.19045) [x86_64]
using SQLite Version 3.46.1
and Qt 5.15.2

まず、DATEフィールドを含むテーブルを使って Browse Data で問題を再現し、次に Copy と Copy with Headers のアクションおよびクリップボードへの出力を追跡します。報告された Windows と SQLite のバージョンで、選択範囲を貼り付けたときに各日付の値が含まれ、要求した場合はヘッダーも保持されれば完了です。
