Line operations issues (CTRL+A on lines, Copy-paste)

[animefn]

Hi,

I am using the latest "Feature Release 11 Latest" on Windows 11.

I noticed that selecting lines then doing copy (via shortcut or menu) then going to another Aegisub windows will only paste 1 line, or sometimes will paste the entire CSV-live raw content inside the text (even If I click outside the textarea).

Also, if I press on 1 line then do ctrl+a this will not select all lines in your fork.

I tried 3.2.2 (official) and wangqr's fork and both do not suffer from these issues...
