'Copy text in Rich Text format' option affects block select copy & paste in v12.8
説明
In 12.8 if you tick the "Copy text in rich text format" option, when you do a Block selection in the Editor - and copy some data, when it is pasted, it does not paste correctly, and the data goes onto other lines. When it is unticked, pasting data works normally.
In 12.7 it works the correct way if the option is ticked or unticked.
