Copy link to clipboard
Mac mini (M1, 2020)
Big Sur 11.2.3 (20D91)
Pasting text copied from TextEdit, over selected text, does not get same properties. It gets properties from neighbouring text.
Confirmed here, in 25.3.1, running under Windows 10—and—confirmed that it worked differently in 25.2.3 prior to update.
Could have something to do with the new Clipboard Handling Preference; "Paste text without Formatting," but changing that setting seems to have no effect on this.
