If you select a line by drawing from the left edge directly down, in an active cell, you get a nice visual indicator that the LF has been selected: the selection color extends to the edge of the text box. And it will copy as a whole line including the LF.
However if you do the same when a cell is inactive, the LF is not copied. You have to (weirdly) select somewhat into the next line where there is an invisible character, in order to get the LF. And of course there is no visual indicator.
This makes it harder to copy and paste a line when the cell is inactive.
Might be difficult to simulate this behavior, but it’s worth a look.
